Just to the south of the town, you will see the cliffs and bays of the Pembroke coast. Here you will find various sites associated with St David, mainly the ruined chapel dedicated to his mother, St Non, where they stay he was born, and to the west, the tiny creek in Porth-Clais port where legend has it he was baptised.

The jetty, massive retaining walls, Fishermen's Chapel and warehouses, backing onto an attractive group of Georgian and Regency houses rising to the cliff top form an attractive picture. Superb sandy beaches extend north and south. Castle Hill has a local museum with paintings by Augustus and Gwen John and other Tenby artists. St Catherine's island with its Victorian fort (1869) is cut off from the mainland at high tide.

The palace as it is seen today was mainly built by bishop Gower (1328-1347). The outer wall is a little older. It is made up of a courtyard lined with three long buildings and a wall with a gate with flying buttresses. The building including the bishop's rooms, kitchen, chapel and women's room was probably the main residence. The great hall in the south of the building was for important guests.

This hilltop fort is the setting for an ambitious attempt to recreate the environment of the Iron Age: storage pit, cultivated areas and a trio of conical thatched huts with smoky interiors.
