St. Catherine's Oratory is a medieval lighthouse on St. Catherine's Down near the southern coast of the Isle of Wight, the Back of the Wight. It was built by Lord of Chale Walter de Godeton (sometimes spelled "Goditon") as an act of penance for plundering wine from the wreck of St. Marie of Bayonne in Chale Bay on 20 April 1313 AD. The lighthouse tower is known locally as the "Pepperpot". The site is too frequently shrouded in fog to be useful for a lighthouse. The current lighthouse, constructed after the 1837 wreck of the Clarendon, was built much closer to sea level.
