Inner North Dock Walls

The Inner North Dock Walls, constructed around 1825-1830 by William Chapman and later revised by Rennie and Telford, are significant structures made of large dressed blocks of Penshaw sandstone, featuring tooled and margined faces. The walls have a trapezoidal shape, enclosing an area of approximately one hectare. The slightly battered pier walls on the north, east, and west sides rise to about 8 metres and still hold some 19th-century cast-iron standards for chain railings. The retaining wall on the south side reaches approximately 15 metres in height and includes a flight of steps at the south-west corner. There is a narrow dock entrance on the south-east side, which is equipped with two hydraulically-operated wooden gates and two cast-iron mooring posts on either side. Additionally, there are two wooden mooring posts located in the center of the dock basin. The attached dock wall to the south-west of the dock entrance is not considered to be of special interest.
