Cask banks

The Cask Banks consist of three raised, roughly triangular areas built for storing casks. The northern bank was constructed around 1850, while the middle and southern banks were built around 1908. These banks are situated to the north of the inner harbour, with the southern bank directly north of the harbour, the central bank serving as a focal green space, and the northern bank located directly north of a former clay store from 1908, which is now the Shipwreck Treasure Museum.

The walls of the northern cask bank are made from a mix of slate stone and granite rubble, capped with concrete, although the east wall appears to have been altered. The walls of the central cask bank are constructed from granite rubble with concrete capping, featuring areas of cobblestones at the south and north corners. This bank also has an indented equilateral triangle on its south side, approximately 2.5 meters deep. The southern cask bank has granite rubble walls with stone and concrete capping, and its north side is level with the road, featuring a granite-block kerb. Cobblestones are present at the east and west corners, and the bank includes two triangular-shaped indents on the south side, each roughly 2 to 2.5 meters deep. The cobbled areas on the banks were added in the later 20th century and are used for displaying historic objects such as anchors.
