Llawhaden Castle, Pembrokeshire
This castle is more a fortified Bishops Palace as opposed to a castle, although it is still located on easily defensible high ground with view of The Vale of the Eastern Cleddau. However, it is very castle like in appearance and there are some impressive remains to visit, particularly the shell of the gatehouse shown above. Llawhaden probably started life in the 12th century and at that time it would have been an earth and timber castle. Various Bishops added to it and reinforced the defences and slowly the castle evolved. It was abandoned following the Dissolution of the Monasteries in the 16th century. The site is now managed by CADW, the Welsh historic buildings agency.
