Description
The Descending Steps from Watch House is a Grade II listed structure featuring a sequence of steep, walled steps and small towers inspired by Mediterranean architecture, built onto exposed rock. The walls are made of rubble and are painted white on the outside, while the towers have hipped roofs covered with red pantiles.
The steps begin at the Watch House and zig-zag down the steep, wooded slope, with a parapet wall on the downward side. About halfway down, there is a small, roofed structure in the form of a square gate tower, which features a round-arched entrance at the front, a horizontal rectangular light above it, and a diagonal slit light to the left. At this point, the steps make a right-angle turn and pass through a short sloped section wall to the northeast via another arched entrance, which has a simple slatted iron gate.
The steps continue to corkscrew downwards and pass through a second similar structure that has an open, loggia-type upper section supported by round columns and a corbel course below. The steps emerge from this structure through another arched opening and proceed through a final half-gated arch within a walled enclosure at the shoreline, with a small boiler house structure to the left.
