Walls of the Outer Basin and West Pier/Quay

The Outer Basin is rectangular, originally built of giant regularly coursed dressed limestone blocks, at S and W directly onto outcropping rock; later rockfaced stone and later small stone patching and repairs. S and W walls are mainly of giant coursed blocks. Later N wall is of rock-faced stone, with clear infill where lockgates were removed when Inner Basin was decommissioned. Further alterations can be traced in masonry of E wall. Stone quaysides, in places covered with concrete or ashphalt, have iron and stone bollards and mooring rings; original steps at NW corner, 2 steps created out of each stone block; an apparently original buttress adjacent; culverts and a blocked arched opening in W wall. Seawall to E has blocks on inner face decoratively snecked; seaward side is rockfaced, mostly large coursed blocks battered to base; raised parapet. The West Pier or Quay in front of Jennings Warehouse is built of coursed dressed blocks with section S of rock-faced stone; grooves for gates, which are apparently submerged and visible in silt at low water.
