WEST PIER: the western harbour pier, which started construction in 1752, runs for approximately 230m south of the crosswall in a south-easterly direction before turning north-east and continuing for approximately 125m to the circular pier head. It is constructed of a chalk and cement core faced with stepped Purbeck stone with a granite coping and stone parapet. The pier head, which was reconstructed under Rennie in 1840, comprises Aislaby sandstone for the lower courses of masonry and Cornish granite for the upper courses. A lighthouse built in 1842 by John Shaw is located at the pier head and is listed separately at Grade II (LE 1086089). Stone flag paving survives although this is largely covered with C20 tarmac, except at the head where the paving is set in a radial pattern. The low coping at the pier head contains inset iron pulleys, or fairleads, which were used to guide boats into the harbour. A vertical iron post located along the inner face of the pier, approximately 77m south-west of the lighthouse and adjacent to the modern gangway, is all that remains of the moveable crane that was erected by Peter Kier in 1802.
