St. Catherine's Lighthouse is one of the oldest lighthouse locations in Great Britain. The first lighthouse was established on St. Catherine's Point in 1323 on the orders of the Pope, after a ship ran aground nearby and its cargo was either lost or plundered. Once part of St. Catherine's Oratory, its octagonal stone tower can still be seen today to the west of Niton at the foot of the Undercliff. It is known locally as the "Pepperpot".
The new lighthouse, built by Trinity House in 1838, was constructed as a Шаблон:Convert stone tower; however, its light was often obscured by fog, which led to its height being reduced by Шаблон:Convert in 1875. It has a range of Шаблон:Convert and is the third-most powerful of all the lights maintained by Trinity House. Another tower, built immediately alongside in 1932, houses the now redundant fog signal (discontinued in 1987).
Trinity House provides tours of the lighthouse year round.
