Two miles east of Pembroke, the bishops of St Davids built themselves a comfortable country retreat. Most of what you see is the work of Bishop Henry de Gower (1328–1347), including a great hall 25 metres long. In its day it had more than twenty rooms, fishponds, orchards, vegetable gardens and a 144-acre deer park. After the Reformation it passed to the Devereux family, later Earls of Essex.
It is a Cadw site in quiet, well-kept grounds, and rarely busy. Enter by the side gate; there is a small car park across the road, and Lamphey station is 600 metres away.
