AKA Smeaton's Tower
The lighthouse was originally built on the Eddystone reef in 1759 at a cost of ??40,000, but was taken down in the early 1880s when it was discovered that the sea was undermining the rock it was standing on.
Approximately two thirds of the structure was moved stone by stone to its current resting place on the Hoe.
