Although called Old Beaupre Castle the structure is seen as a fortified manor house. The original house was an L-shaped building, now located within the inner courtyard, built circa 1300 and from this period until the 18th century it was owned by the Basset family. During the 16th century intensive remodelling was undertaken, started by Sir Rice Mansel, continued by William Basset and completed by William's son, Richard. This additional work added the impressive outer gatehouse, completed in 1586 and a three-storeyed Renaissance porch, completed 1600, along with the buildings around the middle court. The buildings on the west side of the middle court, now roofless, provided luxurious living accommodation with large windows, handsome fireplaces, a fine stone stairway, and numerous privies connected to a drain along which water still flows.
After the 16th century alterations little work was carried out on Beaupre, and after the English Civil War the Basset family fortunes went into decline. At the beginning of the 18th century, the Basset inheritance eventually passed to the Jones family. The Jones family decided not to settle in Beaupre Castle and chose to use the smaller and more convenient mansion of New Beaupre. Beaupre was sold in 1709, and by that time it was in a state of disrepair with only part of it still habitable. Nevertheless, there is some evidence that it continued to be at least partly occupied as various fireplaces and windows were blocked up, presumably to reduce the taxes payable. The southeastern block continues to be occupied up to the present time as a farmhouse and has a separate listing on the historic buildings register.
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.
