This is the view as you come down from the medieval town walls towards Tenby south beach. The island in front is St Catherines Island (Welsh: Ynys Catrin). The island is home to St Catherine's Fort. It is known colloquially as St Catherine's Rock and the area directly in front of it is known as the Catterns. For many centuries a tiny church was the only building on the Island. The remains of the church were demolished when the fort was constructed in 1867.
