Description
Saint Martin's Tower is a tower constructed with whitewashed roughcast, possibly on a concrete base, topped with a bell-cast plain-tiled pyramid roof and deep eaves. The chimney on the southeast roof slope has been removed. The tower has a square plan and consists of three levels, each accessible from the hillside.
On the northeast side of the top floor, there are flying steps leading up to an arched entry with a recessed door on the left and two small casements on the right. Each of the other sides features a pair of narrow loop windows, and the northwest side originally had a clock in the center. The middle level includes an arched door on the northeast side in a flush stone surround, located to the extreme right, along with a small casement in the center, positioned near the steps leading to the top floor. The northwest side features a shallow canted oriel with a configuration of 1-2-1 lights, a flat top, and a deep roughcast lower part that is ogee-moulded at the base. The southwest side has a single loop window in the center.
The bottom level has two small casements on the northwest side and a central pair of tiny sash windows on the southwest side, while the other two sides are built against the rock. Inside, it is said that a few features by Coates Carter remain, including stairs, cupboards, and altered fireplaces.
