Site Description

1739, builder unknown, altered 1820 and 1866, originally coal fired.

William Crispe obtained a patent from Trinity House dated 2 June 1737 and he and his partner Benjamin Lund built the tower which is said to have first shown its light on 25 March 1738. Top of tower rebuilt 1820 when taken over by Trinity House and an oil lantern was fitted. 1839 lamps were replaced with dioptric apparatus and in 1866 a new lantern was fitted with helical glazing, a new powerful optic and a new iron gallery. This increased the height of thetower to 30/18m (99ft).
