Gastown is a national historic site in Vancouver, British Columbia, at the northeast end of Downtown adjacent to the Downtown Eastside. Its historical boundaries were the waterfront (now Water Street and the CPR tracks), Columbia Street, Hastings Street, and Cambie Street, which were the borders of the 1870 townsite survey, the proper name and postal address of which was Granville, B.I. ("Burrard Inlet"). The official boundary does not include most of Hastings Street except for the Woodward's and Dominion Buildings, and stretches east past Columbia St., to the laneway running parallel to the west side of Main Street.
Gastown was Vancouver's first downtown core and is named after "Gassy" Jack Deighton, a Yorkshire seaman, steamboat captain and barkeep who arrived in 1867 to open the area's first saloon. The town soon prospered as the site of Hastings Mill sawmill, seaport, and quickly became a general centre of trade and commerce on Burrard Inlet as well as a rough-and-rowdy resort for off-work loggers and fishermen as well as the crews and captains of the many sailing ships which came to Gastown or Moodyville, on the north side of the inlet (which was a dry town) to load logs and timber. The Canadian Pacific Railway terminated on piles on the shore parallel to Water Street in 1886. From this the area became a hive of warehouses. Carrall Street was particularly swampy owing to it being low ground between False Creek and Burrard Inlet. Bridges overcame this obstacle, and the low ground and beach was slowly filled in with refuse. In 1886 the town was incorporated as the City of Vancouver. It fell victim to the Great Vancouver Fire that same year, losing all but two of its buildings, but the area was completely rebuilt and continued to thrive. Hastings and Main was the traditional centre of town, and the foreshore became an important staging area with the North and West Vancouver Ferries, and Union Steamships all having docks there. Evans, Coleman, Evans, a longtime merchandiser, had a warehouse; Fleck Brothers, and Koret distributors also had buildings. Department stores such as Spencer's, Hudson's Bay Company warehouse, Woodward's, Fairbanks Morse, Army and Navy stores, and food retailers Malkins and Kelly Douglas traded and were based there.
Gastown found new life as the centre of the city's wholesale produce distribution until the Great Depression in the 1930s. It was also the centre of the city's drinking life: there were 300 licensed establishments the twelve-block area of the former Granville. After the Depression Gastown was a largely forgotten neighbourhood of the larger city and fell into decline and disrepair as a continuation of the Skid Row area with cheap beer parlours, flophouse hotels, and loggers' hiring halls.
In the 1960s, citizens became concerned with preserving Gastown's distinctive and historic architecture, which like the nearby Chinatown and Strathcona was scheduled to be demolished to build a major freeway into the city's downtown. A campaign led by businessmen and property owners, as well as the counterculture and associated political protestors, pressured the provincial government to declare the area a historical site in 1971, protecting its heritage buildings to this day. A riot between the hippies and the police in 1971 over marijuana has gone into legend, the incident now made public on the Woodwards building, a throwback to the more serious Post office riot of 1938.
Gastown is a mix of "hip" contemporary fashion and interior furnishing boutiques, tourist-oriented businesses (generally restricted to Water Street), restaurants, nightclubs, poverty and newly upscale housing. In addition, there are law firms, architects and other professional offices, as well as computer and internet businesses, art galleries, music and art studios, and acting and film schools.
In February 2013 The Gastown Gazette began publishing local news and stories about the ongoing protests against gentrification in the Downtown Eastside and Gastown area of Vancouver. The community paper has since gathered provincial and national attention for its uncompromising and hard-hitting reports on the neighborhood.
Gastown has become a hub for technology and new media. It has attracted companies such as Zaui Software, Idea Rebel, MetroQuest, BootUp Labs Entrepreneurial Society, SEOinVancouver and MarketR.
In June 2004, Storyeum opened in Gastown. It was a lively theatrical 65-minute show that re-enacted the history of BC using eight sets that were all located below street level. Unfortunately, due to mounting debt, the attraction closed its doors in October 2006.
Tourists are entertained by the Gastown steam clock in Vancouver
Gastown Steam Clock Plaque
Gastown's most famous (though nowhere near oldest) landmark is the steam-powered clock on the corner of Cambie and Water Street. It was built in 1977 to cover a steam grate, part of Vancouver's distributed steam-heating system, as a way to harness the steam and to prevent street people from sleeping on the spot in cold weather. Its original design was faulty and it had to be powered by electricity after a breakdown. The steam mechanism was completely restored with the financial support of local businesses as it had become a major tourist attraction, and is promoted as a heritage feature although it is of modern invention. The steam used is low pressure downtown-wide steam heating network (from a plant adjacent to the Georgia Viaduct) that powers a miniature steam engine in its base, in turn driving a chain lift. The chain lift moves steel balls upward, where they are unloaded and roll to a descending chain. The weight of the balls on the descending chain drives a conventional pendulum clock escapement, geared to the hands on the four faces. The steam also powers the clock's sound production as whistles are used instead of bells to produce the Westminster "chime" and to signal the time. In October 2014 the clock was temporarily removed for major repairs by its original builder, and should have been reinstalled by January 2015. 
The Gastown Steam Clock appears on the cover of the 2011 Nickelback album Here and Now and is also featured in a scene from the 1991 Chuck Norris action film The Hitman.
Bars (a different licensing category in Vancouver) include 19 Below, The Cambie, Chill Winston, Columbia Club, Lamplighter Public House, One Lounge, Revel, The Annex, and The Columbia. Mao Mao Bistro, a former club, has since been replaced by The Greedy Pig. The Town Pump, had been a live music venue since the hippie era of the 1960s. The Blarney Stone is one of Vancouver's Irish-style party houses.
^"Gastown Steam Clock undergoes repairs". City of Vancouver. City of Vancouver (B.C., Canada). 2014-10-08. Retrieved 1 January 2015. The mechanical moving parts of the Steam Clock’s device for loading the metal balls have worn over the last 37 years and can no longer be reliably maintained. Mechanical failures have been a common occurrence in the past year, and the proposed repairs to the ball loading device will restore reliability to the Steam Clock while maintaining its historical integrity.
