Clough Castle is an excellent example of an Anglo-Norman castle with an added stone tower. A small kidney-shaped bailey lies south of a large mound, originally separated from it by a 2.1m deep ditch. On top of the 25 ft high motte is a stone tower, enlarged to become a tower house in the 15th century. It is sited off-centre as much of the rest of the top of the motte was occupied by a large hall, which apparently burned down. Around the motte is a ditch, and on the south-east side a low crescent shaped bailey, which was probably once joined to the motte by a wooden bridge.
Excavations on the summit of the mound in 1950 revealed that originally (in the late 12th or early 13th century) the top of the motte was surrounded by a timber palisade within which were pits for archers. Also found was the foundation of a long rectangular hall in the north-east half of the area, probably built in the mid 13th century. Later in the same century a small rectangular stone keep was built to the south-west, two storeys high and surviving to this day, having been conserved in 1981-82. In the late Middle Ages, after what appears to have been a period of disuse, it was restored and added to, resulting in an L-shaped tower house.
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.
