The moat and round tower of Pencoed Castle may date from 1270 by Sir Richard de la More. It passed to the Morgans of Tredegar in the 15th century and a big new mansion on the east side and the gatehouse on the west side were built by Sir Thomas Morgan in c. 1490-1500. The gatehouse and corner tower are ruined and the mansion lies in a gutted and derelict state, though still with some flooring and the roof more or less intact.
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.
