High Light (Lighthouse Attached to Rear Wing of Number 8)

High Light is a lighthouse attached to the rear wing of Number 8, built between 1780 and 1790. It was heightened twice in the late 19th century and early 20th century. The lower part of the lighthouse is made of squared stone from the 18th century, while the upper sections are constructed of brick and are colour-washed. The tower is slightly tapered and circular, with the lower part divided into four stages by horizontal bands. There is a doorway on the north side, which is sheltered by a small added porch. The lighthouse features quatrefoil or cross loops at the cardinal points, some of which are blocked. The upper part has two bands on moulded corbels and two windows facing south. The flat roof is surrounded by a railing supported by knobbed spiral standards.

Inside, the 18th-century section contains a stone newel stair, and there are ladders in the top section. The lighthouse operated alongside the Low Light, which was rebuilt in 1936, until 1985, when it was replaced by modern navigation aids and repainted in a mushroom colour instead of white.
