Landward is a good stretch of the town walls, enclosing a characteristically intricate web of medieval streets, widening out at St Mary's, one of Wales' largest parish churches, with a 46 m-high spire. The Tudor Merchant's House, virtually unchanged, has Flemish fireplaces and period furniture.

The Pembrokeshire Peninsula abounds in megaliths and dolmens, such as the cromlech of Pentre Ifan. Christianity has also left its mark as can be seen inside St David's Cathedral (12C-13C) and Pembroke Castle. In 1952 the coastline was designated a National Park; it is the smallest National Park but also that with the most coastal scenery. It boasts a wonderful variety of beaches, some delightful seaside towns, such as Tenby, and a cliffline that is often as spectacular as Stacks Rocks.

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.
