Cadw's description

On the N side of Lock House at the foot of Lock Hill.

The Neath Canal was begun in 1791 and opened in 1794. Traffic ceased in 1921. The lock is an original feature of the canal.

The lock chamber is built with coursed stone walls and flat stone copings. At the E end is a concave brick wall with integral sluice, heightened in order to dam the water further E. At the W end are the partial remains of 2 lock gates. Over the W end of the lock is a renewed bridge with stone parapet and concrete decking.

Listed for its industrial archaeological interest as an integral component of the most complete depot of any of the South Wales canals.
