Gas Street Basin is a canal basin in the heart of Birmingham where the Worcester and Birmingham Canal meets the BCN Main Line.

Situated off Broad Street, between the Mailbox and Brindleyplace developments, it marks the northern terminus of the 29-mile Worcester and Birmingham Canal.

The basin has a notable historical feature: the Worcester Bar, a physical barrier that for twenty years prevented direct connection between the two canal networks.

An 1815 Act of Parliament finally authorised the bar lock, allowing boats to pass between the systems. Toll offices on either side collected charges for each company.

Today the basin retains much of its historic character, with traditional narrowboats and cast-iron footbridges alongside modern waterside bars and restaurants.

It serves as a popular starting point for towpath walks along the Worcester and Birmingham Canal toward Worcester, 58 locks and roughly 30 miles to the south.
