[1] Deep Cutting was the name of the short stretch of canal between the junction and Broad Street Tunnel.
[1] The Birmingham Canal Company head office was built at the end of the Paradise Street Branch, where there were wharves along the side of a pair of tuning fork shaped basins.
This was Old Wharf, later partly filled in and built upon, leaving the present day Gas Street Basin.
The island was installed during World War II, to allow the use of temporary dams to protect the railway tunnel beneath it, should the canal be breached by bombing.
To the South-East is the International Convention Centre and Gas Street Basin, where the BCN ends and the Worcester and Birmingham Canal begins.
