St Catherine's Point is the southernmost point on the Isle of Wight. It is close to the village of Niton and the point where the Back of the Wight changes to the Undercliff of Ventnor. On nearby St Catherine's Down is St Catherine's Oratory, locally known as the "Pepperpot", a stone lighthouse built in the 1323 by Walter De Godeton. It is Britain's oldest medieval lighthouse. There was an attached chapel at one time, but it has been long demolished. There is a Bronze Age barrow nearby which was excavated in the 1920s.
