Top Lock

Top Lock is a brick-lined lock chamber featuring stone copings. It has timber gates that were replaced in the 1980s. The lock includes cast-iron lock ground-sluice controls, likely introduced by G W Buck, who was the Montgomeryshire Canal Eastern Branch Engineer between 1819 and 1831. There is a brick retaining wall that supports the platform above the falling tow-path to the northeast of the lock, as well as a retaining wall on the high western bank that connects the lock chamber to bridge No. 111, which is located immediately to the north. Additionally, there is a small brick hut on the western side of the lock.
