Gas Street Basin (grid reference SP062866) is a canal basin in the centre of Birmingham, England, where the Worcester and Birmingham Canal meets the BCN Main Line.
The Worcester Bar, a 7-foot-3-inch-wide (2.21 m) straight barrier 84 yards (77 m) long was built perpendicular to the run of the two canals.
It is connected to Gas Street via a footbridge reconstructed to a design by Horseley Ironworks of the 19th century.
The wall and ramp down from Gas Street, the Tap and Spile pub, and the neighbouring building are all grade II listed, as is the Martin & Chamberlain building built on top of the Broad Street Tunnel.
A canal-side cottage there was used as the home of a character in the long-running soap opera Crossroads.
