Fan Tan Alley

Fan Tan Alley is an alley in the Chinatown neighbourhood of Victoria, British Columbia, Canada that is known for being the narrowest commercial street in North America, being less than 0.9 m wide at its narrowest point. It runs south from Fisgard Avenue to Pandora Avenue at the block between Government Street and Store Street. Named after the Chinese gambling game Fan-Tan, the alley was originally well known for opium factories that produced opium until it was made illegal in 1908.
