Lock Keepers Office

The Lock Keeper's Office is an office building located at the west end of the fourth lock, likely built around 1816. It is constructed from coursed stone and features a slate roof with stone gable copings and a chimney at the rear gable. The building has a square single-cell plan and is built into a slope, making it one storey on the road (north) side and two storeys on the south side. The gabled front faces the bridge and includes a board door on the right, which is accessed by a stone step that is protected on two sides by iron railings with a ramped handrail. There is also a fixed window with four large panes in a plain stone case. On the south side, there is a boarded basement door with a large lintel, a small basement window, and a top-hung casement window above.
