Roch Castle was built by Norman knight Adam de Rupe in the second half of the 12th century, probably on the site of an earlier wooden structure. After the deRupe family died out in the 15th century, the Castle was taken over eventually in the 17th century by the Walter family. Their daughter Lucy was born in the castle, and later became a courtesan of Charles II, and bore him an acknowledged son James, 1st Duke of Monmouth.
During the English Civil War, the Walter family declared for King Charles I. Although Pembrokeshire was initially Royalist, the Puritans gained the upper hand. The castle changed hands twice, before the Walter family fled when it was captured for a second time by the Parliamentary forces and subsequently burned in 1644. It lay dormant and unclaimed until the return of Duke of Monmouth, who led a rebellion and was captured at the Battle of Sedgemoor, and then beheaded on 15 July 1685.
The castle remained decaying until 1900, when purchased by John Philipps, 1st Viscount St Davids, who restored it with a steel frame and new concrete floors to the designs of D. E. Thomas of Haverfordwest. Further works were carried out in 1910 and circa 1918–20, the latter by D. F. Ingleton.
The Castle was purchased in 2008 by Keith Griffiths for the Griffiths-Roch Foundation and was restored for operation by the Retreats Group as a six-bedroom luxury hotel Roch Castle Hotel.
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.
