Causeway at Letheringham Old Hall

The causeway at Letheringham Old Hall dates from the 15th or 16th century and carries the drive across a moat. It is constructed mainly of brick in header bond, with some patches of 18th or 19th-century brick in random bond. The lower part of the causeway has solid walling without any archway, topped with 19th-century brick coping. The north face features the remains of a polygonal buttress on the right side, while the south face is similar but lacks the polygonal buttress and has some patching in white brick. Alongside the causeway, running south along the western bank, is a revetment from the 15th or 16th century. This includes the base of a polygonal projection on the far left, some cement-rendered sections, shoring buttresses on the right, a further projecting portion of ashlar on the right (possibly the base of a garderobe tower), and a stretch of patched brick walling further to the right.
