Cask banks

Three cask banks; the north built around 1850 and the middle and southern around 1908.

The cask banks comprise raised roughly-triangular areas with retaining stone walls approximately 800mm high. They are located to the north of the inner harbour with the southern bank directly to its north; the central bank acting as a focal green space; and the north bank is located directly to the north of a former 1908 clay store (now the Shipwreck Treasure Museum).

The walls to the northern cask bank are constructed of a mix of slate stone and granite rubble and are capped with concrete; the east wall has probably been altered. The central cask bank walls are granite rubble with concrete capping, and at the south and north corner of the raised bank are areas of cobblestones. On its south side is an indented equilateral triangle roughly 2.5m deep. The southern cask bank has granite rubble walls with stone and concrete capping, but the north side is level with the road and has a granite-block kerb. There are areas of cobblestones at the east and west corners. The bank also has two triangular-shaped indents on the south side, roughly 2m to 2.5m deep. The cobbled areas on the banks are later-C20 and used for the display of historic objects such as anchors.
