Pacific Central Station in Vancouver

There are about 2,150 registered heritage buildings in Vancouver, plus 131 parks and trees, and additional monuments and archaeological sites.

You can find all of these heritage sites in the Vancouver Heritage Register (VHR).

The City's long term goal is to protect, through voluntary designation, as many resources on the Vancouver Heritage Register as possible.

How does a site qualify for inclusion?

To be included in the VHR:  

  • Sites must have architectural and historical significance
  • The context of the building and its surroundings must still be clear
  • Alterations to the exterior of the building must be limited
  • The building must have been constructed before 1940, with the exception of "recent landmarks"

Vancouver Boundaries

The boundaries of the City of Vancouver are not simple, check out their complicated description from the Vancouver Charter below. Does this make any sense to you?

Commencing at a point in the First Narrows of Burrard Inlet, which point is eight hundred (800) feet distant northerly, measured along a line astronomically north from the light in Prospect Point Lighthouse; thence south-easterly in a straight line to a point in Burrard Inlet on the production northerly of the boundary between District Lot Five hundred and forty-one (541) and District Lot One hundred and eighty-five (185), which point is situate at the intersection of the said production with the straight line from the light in Brockton Point Lighthouse to a point in the Second Narrows of Burrard Inlet distant five hundred (500) feet northerly, measured along the production northerly of the easterly boundary of the Town of Hastings from a boundary survey monument set at or near the high-water mark for the southerly shore of Burrard Inlet and on the said easterly boundary of the Town of Hastings; thence easterly along the aforedescribed straight line to the aforesaid point on the production northerly of the easterly boundary of the Town of Hastings; thence southerly, following in succession along the said production northerly of the easterly boundary of the Town of Hastings, the said easterly boundary of the Town of Hastings, the easterly boundary of District Lot Thirty-six (36), the easterly boundary of District Lot Forty-nine (49), the easterly boundary of District Lot Three hundred and thirty-nine (339), the easterly boundary of District Lot Three hundred and thirty-five (335), the easterly boundary of District Lot Three hundred and thirty-one (331), and along the production southerly of the said easterly boundary of District Lot Three hundred and thirty-one (331) to intersection of the same with a line drawn parallel to and two hundred (200) feet perpendicularly distant southerly from low-water mark of the north bank of the North Arm of Fraser River;

In 1912 Dominion Blue Print & Drafting Company makes its debut in the city directory. It is one of eight companies involved in blueprints. A half page ad on page 226 of the 1912 directory indicates that Dominion Blue Print & Drafting Company, located at 36 Bank of Hamilton Building (432 Hamilton St.), is a Maker of Maps, Blueprints, Brown Line, and Blue Line Prints.

The first professional hockey game ever played in Vancouver took place on January 5, 1912, it was enjoyed by the crowd at the Patrick brothers’ Denman Arena. The Vancouver Millionaires beat the New Westminster Royals 8 to 3. In 1915, they won the Stanley Cup. The finals were played in Vancouver, with Games 1, 3, and 5 played under Pacific Coast Hockey Association (PCHA) rules. The Millionaires became the first team from the PCHA to win the Cup.

The 270-foot (82.3-metre) tall World Building went up at 100 West Pender. We know it today as the Old Sun Tower. John Coughland and Sons of Vancouver fabricated 1,250 tons of steel for what was then the tallest building in the British Empire. It held that title for two years. (The caryatids on the building, the “Nine Maidens,” were created by sculptor Charles Marega.)

On February 12, 1912 the Vancouver Morning Sun first appeared. Later, it will become an afternoon newspaper, the Vancouver Sun. When the Sun began operation, it was published at 125 West Pender Street, just around the corner from The Province, its rival at the time. In 1924, the Sun bought the Vancouver World newspaper, which had been in financial difficulty for some time. In March 1937, a fire destroyed the Sun's business and editorial offices. The only casualty was the janitor, who suffered minor burns and smoke inhalation. The Sun promptly moved across the street into the World Building, where the World had been published. The building was accordingly renamed the Sun Tower. The paper moved to Granville Square in 1997.

On March 15, the municipality of West Vancouver was incorporated. The population was 700. Land for the city hall was donated by John Lawson, called by some the "father" of West Vancouver. (Population in the summers went up to 1,200.) The first municipal election was held on April 6, 1912. In November 1938, the Lions Gate Bridge was opened to traffic, allowing extensive growth of the semi-populated community, previously only accessible by ferry. Some homes in West Vancouver date back to the 1920s and 30s, though most of the currently existing dwellings were built in the 1970s and 80s, and mostly in British Pacific Properties' developments.

On March 30th the Vancouver local of the International Longshoremen's Association was formed, with 60 charter members. Also that March, Emily Carr, back from a sojourn in France, exhibits paintings she created there in her gallery at 1465 West Broadway.

On September 18th, Canada’s Governor General, the Duke of Connaught (a famous soldier and a son of Queen Victoria), visited Vancouver with the Duchess to officiate at the ceremony naming the brand-new Connaught Bridge—a name that never caught on. Everyone called it the Cambie Street Bridge. (It was demolished in 1985, replaced by the present bridge.) The royals were accompanied by their daughter, Princess Patricia, the woman for whom the Princess Patricia’s Canadian Light Infantry (PPCLI) is named; she was the regiment’s colonel-in-chief.

The Connaughts officially opened the provincial courthouse, too. James Findlay was the first Vancouver mayor to wear the new gold civic chain of office. That was for the royal visit.

Also in 1912, the Lee Building at Broadway and Main went up. That’s the one with the huge billboard atop it. The CPR Station opened at 601 West Cordova. Contractor was Westinghouse, Church, Kerr & Co. Today the beautiful old building is the western terminus for the SkyTrain and the West Coast Express, and the southern port for the SeaBus. Charlie Chaplin and Stan Laurel performed in Vancouver with a music hall troupe from England, “Karno's Comedians.” A 250-pound Vancouver policeman, Duncan Gillis, became the first Olympic medal winner from B.C., winning silver at Stockholm in the hammer throw. (48.39 metres.)

Most of us have grown up with Oreo cookies, and 100 years ago the Oreo cookie, was born. In 1912, Nabisco had a new idea for a cookie - two chocolate disks with a creme filling in between. The first Oreo cookie looked very similar to the Oreo cookie of today, with only a slight difference in the design on the chocolate disks.

So how did the Oreo get its name? The people at Nabisco aren't quite sure. Some believe that the cookie's name was taken from the French word for gold, "or" (the main color on early Oreo packages). Others claim the name stemmed from the shape of a hill-shaped test version; thus naming the cookie in Greek for mountain, "oreo." Still others believe the name is a combination of taking the "re" from "cream" and placing it between the two "o"s in "chocolate" - making "o-re-o." And still others believe that the cookie was named Oreo because it was short and easy to pronounce.

No matter how it got named, over 362 billion Oreo cookies have been sold since it was first introduced in 1912, making it the best selling cookie of the 20th century.

The Railway Club - Dunsmuir and Seymour

In 1903 Mrs Thrythall was listed in the Building Permit Register owner, architect and developer of a frame store and dwelling at the corner of Dunsmuir and Seymour. Her husband, William, was one of the earlier printers in the city, setting up shop in 1888 with his son, also called William. The 1903 insurance map shows the corner developed with a printers office (electric motor) with offices above. The additions seem to have been further east, along Dunsmuit Street. The family name is recorded as both Thrythall and Trythall, so there’s some confusion, but Trythall seems to be correct. The company was still operating from the Seymour address in 1920, although a year later they have moved to Homer Street. Most history associated with the family is connected to Mt Trythall’s cabin, halfway up Grouse Mountain – when a climb to the summit took three days to accomplish.

Some time in the mid to late 1920s when this picture is thought to have been taken a new building was erected. It’s identified by the City Archives as the Lawsen Building – although there don’t seem to be any residents of the city called Lawsen in the late 1920s or early 1930s. But there was a Viggo Laursen, who was a solicitor for the BC Electric Railway Co, and he seems to be the likely owner. Viggo was born in Denmark but had arrived in 1893 with his parents, John and Mary, joining his brother, Otto, a plumber, who had arrived two years earlier. We’ve failed so far to identify the architect or builder.

By 1932 The Railway Club began as a members only card club for railway workers. Known initially as the Railwaymen’s Club, it was one of many membership only workingman clubs opened in the city after prohibition was lifted. The club occupied space once occupied by the European Concert Cafe on the upper floors of the Laursen Building. The club operated with a rare “red circle” license where card clubs like the Marine Club and Logger’s Social Club were given a choice by the government, stop the cards or the sale of liquor. Today the Railway Club continues to operate as a bar and live music venue with one of the most eclectic selections of music in the city.

Bank of Ottawa - West Hastings Street

Here’s the Bank of Ottawa on the corner of Seymour and West Hastings in 1912. The new eight storey building was designed by W Marbury Somervell, but probably slightly changed by Somervell and Putnam (as it has a 1911 building permit in their name). It cost $225,000, and pictures of the construction show a reinforced concrete frame rather than all steel. The building bears a very strong resemblance to the BC Securities Building which is three blocks away and completed a year later to HS Griffith’s design.

The speed that construction could be completed on commercial buildings can be seen from the Contract Record report of September 1910. Work was just starting on the building site, clearing the existing buildings and excavating the basement, and it was expected the whole thing would be complete by May 1911, with occupancy coming a month later. There were 16 offices per floor above the banking floor, and the quality of the building was obviously aimed at all the other office buildings competing for tenants “The entrance to the vestibule and lobby will be handsomely done in marble, while the floors above will be trimmed throughout in birch and finished with mahogany. Other features of this latest addition to Vancouver’s tall buildings will be a vacuum heating system throughout, hot and cold water in all the offices, the Durham plumbing system, mail chute equipment, vacuum cleaning system for all the offices, and commodious toilet rooms on every floor.” The successful contracting bid came from McDonald and Wilson who started work in October 1910 and as far as we know completed on time.

In 1919 the Bank of Ottawa were merged with the Bank of Nova Scotia, and it stayed a branch of the new owners for over 30 years. In 1956 noted local architects Sharp, Thompson, Berwick and Pratt were given the design job of enlarging the bank building. The new project stripped the old building to its frame, replaced the small tobacco store with the billiards room behind (The Maple Leaf Club in 1946) that was next door and the restaurant with rooms over beyond that, and created a simple new office building which was nearly twice the size of the original. A more recent building upgrade in 1987 added an elegant projecting metal cornice to the building.

Carnegie Library

By the late 1890s the city was in need of a library - a real library rather than a room in another building. American philanthropist Andrew Carnegie was funding libraries all over North America, and Vancouver was viewed favourably for an investment in literature. (There were 125 Carnegie Libraries in Canada, almost all in Ontario, but Victoria and New Westminster got one too). G W Grant was hired to design the building, which was most definitely outside the CPR part of town, on the south-west corner of Westminster (Main) and Hastings. Carnegie donated $50,000 on the basis that the City would donate a site and spend $5,000 a year on running the library.

Work started in 1902 and nearly two years later the library opened. It was located next door to the new City Hall. An earlier City Hall was located at Powell Street in 1888. In 1898 the City moved to the building you can see to the south of the library. It was originally erected in 1889 as a market hall designed by C O Wickenden. It was built of Bowen Island bricks where Mayor David Oppenheimer had a financial interest in the brickworks. Unfortunately the clay, or the firing, wasn’t the finest, and Wickenden had to hastily change the design to add two buttressing towers to make sure the building stayed up.

In 1929 with the amalgamation of two other cities into Vancouver larger premises were needed and Council decamped to the Holden Building, an existing office also altered to become City Hall.

The Library stayed until the early 1950s, taking over the former City Hall as an Annex. After the Library moved to their new building on Burrard Street the Museum used the Carnegie building, and the old City Hall was demolished in 1958. After threats of demolition the renovated Carnegie Centre opened as a social service centre for the Downtown Eastside in 1980, incorporating a branch library and with a subtle addition designed by Downs Archambault to the south.

The Sectional Map and Street Directory was the brainchild of a man named Robert Morton. Morton was born in Glasgow, Scotland in 1856. He immigrated to Winnipeg in 1911, then moved to Vernon, BC, for about five years, and then to Calgary.

In 1931-32 Morton moved to Vancouver and took up residence at 2119 Maple Street. He began publishing a section map booklet and street index of the city because an ordinary map of Vancouver was too bulky to carry around. The booklet covered Vancouver, Burnaby, New Westminster, North Vancouver, West Vancouver, Surrey, Maillardville, Lulu Island, and Sea Island. Morton himself went door to door selling his booklets, and was still doing so at the age of 87 in 1942.

Of course maps are full of street names, and where exactly did all those street name come from? Who was Hastings Street named for? How about Hornby? Or what’s the story behind the naming of Charles Street? Now, thanks to the Vancouver Historical Society, which commissioned the work from Elizabeth Walker, and to the Vancouver Public Library, which has put it on line, you can get the answers to those and other questions.

History of The Blueprint

The cyanotype process, also known as the blue print process was invented by Sir John Herschel in 1842 and is still performed today by many darkroom enthusiasts. Herschel made numerous important contributions to photography. He made improvements in photographic processes, particularly in inventing the cyanotype process and variations (such as the chrysotype), the precursors of the modern blueprint process. He experimented with color reproduction, noting that rays of different parts of the spectrum tended to impart their own color to a photographic paper. He collaborated in the early 1840s with Henry Collen, portrait painter to Queen Victoria. Herschel originally discovered the platinum process on the basis of the light sensitivity of platinum salts, later developed by William Willis.

In 1861 Alphonse Louis Poitevin, a French chemist, found that ferro-gallate in gum is light sensitive. Light turns this to an insoluble permanent blue. A coating of this chemical on a paper or other base may be used to reproduce an image from a translucent document.

The ferro-gallate is coated onto a paper from aqueous solution and dried. The coating is yellow. In darkness it is stable for up to three days. It is clamped under glass and a light transmitting document in a daylight exposure frame, which is similar to a picture frame. The frame is put out into daylight requiring a minute or two under a bright sun or about ten times this under an overcast sky. Where ultra-violet light is transmitted the coating converts to a stable blue or black dye. The image can be seen forming, when a strong image is seen the frame is brought indoors and the unconverted coating, under the original image, is washed away. The paper is then dried.

The result is a copy of the original image with the clear background area rendered dark blue and the image reproduced as a white line. The image is stable.

Later other blueprint processes based on photosensitive ferric compounds were used. The best known is probably a process using ammonium ferric citrate and potassium ferricyanide. In this procedure a distinctly blue compound is formed and the process is also known as cyanotype. The paper is impregnated with a solution of ammonium ferric citrate and dried. When the paper is illuminated a photoreaction turns the trivalent (ferric) iron into divalent (ferrous) iron. The image is then developed using a solution of potassium ferricyanide forming insoluble ferroferricyanide (Turnball's blue identical to Prussian blue) with the divalent iron. Excess ammonium ferric citrate and potassium ferricyanide are then washed away.

This is a simple process for the reproduction of any light transmitting document. Engineers and architects drew their designs on cartridge paper; these were then traced on to tracing paper using Indian ink for reproduction whenever needed.

Traditional blueprints have largely been replaced by more modern, less expensive printing methods and digital displays. In the early 1940s, cyanotype blueprint began to be supplanted by diazo prints or whiteprints, which have blue lines on a white background; thus these drawings are also called blue-lines or bluelines. Other comparable dye-based prints are known as blacklines.

Diazo prints remain in use in some applications but in many cases have been replaced by xerographic print processes similar to standard copy machine technology using toner on bond paper. More recently, designs created using Computer-Aided Design techniques may be transferred as a digital file directly to a computer printer or plotter; in some applications paper is avoided altogether and work and analysis is done directly from digital displays. Another common modern method of copying is the use of large-format scanners. These digitize an image which can then be printed with a large-format plotter.

As print and display technology has advanced, the traditional term "blueprint" has continued to be used informally to refer to each type of image.

1912 - The World Building

In 1912 Dominion Blue Print & Drafting Company makes its debut in the city directory. It is one of eight companies involved in blueprints. A half page ad on page 226 of the 1912 directory indicates that Dominion Blue Print & Drafting Company, located at 36 Bank of Hamilton Building (432 Hamilton St.), is a Maker of Maps, Blueprints, Brown Line, and Blue Line Prints. Horace N. Clarke is listed as the Manager.

The newly completed World Building, located at the corner of Pender and Beattie Streets, was commissioned by L. D. Taylor to house his newspaper, The Vancouver World. It was designed by architect W. T. Whiteway, who also designed the original Woodward's building nearby. The intention was that the building would be visible throughout the World's circulation area as the tallest building in the city. John Coughland and Sons of Vancouver had 1,250 tons of steel fabricated for construction.

It is known for its faux-patina steel dome painted to imitate copper cladding. Nine nude muses, the "nine maidens" supporting the cornice line can be seen. The terracotta for this building, including the ladies, was made in Tamworth, Staffordshire, England by Gibbs and Canning Limited.

When it was completed in 1912, it was called The World Building and was the tallest building in the British Empire at 82 m (269 ft), surpassing the previous record-holder, the Dominion Building located just around the corner. For two years, it was the tallest building in Canada until Toronto's 20-story Optima Business Centre opened in 1914. In 1918, droves of Vancouverites turned out to watch as Harry Gardiner, the "Human Fly", scaled the outside of the building. When The Vancouver Sun bought the building in 1937, it was renamed. Although The Sun newspaper has long since relocated, first to South Granville then to Granville Square, the building has retained the name.
