Caldey Priory is on Caldey Island off the coast of Pembrokeshire, Wales, some 300 metres south of the modern Caldey Abbey. Sir Robert fitz Martin was granted the island in 1113 and his mother Geva founded the priory as a daughter house of the Tironensian St. Dogmaels Abbey in the 12th century. It was probably built on a preexisting Celtic Christian site, and lasted to the Dissolution of the Monasteries in 1539, although the number of monks resident there ranged from one in the late 12th century, four in 1402 and six in 1504. The buildings were significantly upgraded in the 16th century after the priory was secularized, but there is no evidence that they were used by either of the owning families of the time.
Several centuries later they were used as a farm house, centered on the priory's church. Around 1800 they became the farm buildings for a new house built for Thomas Kynaston, owner of the island from 1798. Restoration of the buildings may have begun as early as the mid-1890s, but the Rev. W. D. Bushell began the restoration after he bought the priory in 1897. He sold the property in 1906 to the Anglican Benedictine community that built the current abbey, but rented the house and the priory until he died in 1917. The house was subsequently demolished in the 1970s.
The priory buildings are built from rubble stone, with slate roofs, and are grouped around a small courtyard. Over the centuries they have been altered many times and have a very complex history. On the north side was a domestic range that has not survived. The gatehouse is on the western side and there is a two-storey dormitory with a tower on the eastern. The church stands on the south side, and consists of nave, chancel and west tower with a spire.
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.
