Lamphey Bishop's Palace is a ruined medieval building complex in Lamphey. Whilst early thirteenth-century fragments from the old hall still exist, the palace, including the 25 metres great hall, was largely constructed under Bishop Henry de Gower, Bishop of St David's (1328–1347) and was used by high-ranking clergy. The palace was built in three stages and originally had over 20 rooms and featured fishponds, orchards, fruit and herb gardens and areas of parkland with grazing deer.
The palace was surrendered to the crown in 1546 during the reign Henry VIII and granted to Richard Devereux and subsequently the Earls of Essex. Walter Devereux, 1st Earl of Essex lived in the palace as a child. The palace was sold to the Owens of Orielton in 1683, possibly due to damage in the English Civil War. The buildings were possibly used for farm purposes in this era.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
