Description
Boar's Bridge is a bridge over a tributary of the River Tamar, built in the mid to late 19th century. It is constructed of slatestone rubble with granite dressings. The bridge features three round arches, which have slatestone arch rings and a granite keystone. On the upstream side, there are two low triangular cutwaters. The parapet walls are made of rubble and topped with rounded granite coping stones, standing about 80 centimetres high. The bridge measures approximately 7 metres long and 3 metres wide. Boar's Bridge is marked on the 1545 estate map of Cotehele.
