Mathern Palace is a Grade I listed building in the village of Mathern, located south-west of Chepstow close to the Severn Estuary. Between about 1408 and 1705 it was the main residence of the Bishops of Llandaff. After falling into ruin, it was restored and its gardens laid out between 1894 and 1899 by the architectural writer Henry Avray Tipping. In recent years it has been in private hands and used as a guest house.
The palace is approached through the remains of an early 15th-century gateway, on either side of which is a cottage designed by Tipping. The main building itself has an undemonstrative irregularity, suggesting that the bishops had relatively poor resources, and modified the building incrementally.
The gardens lie to the north-west, south-east and south-west of the house. Tipping laid out terraces on the south-west facing slope, and converted the remains of medieval fishponds into ornamental ponds. To the south-east he laid out formal lawns, a kitchen garden, and a sunken rose garden, with the various elements being linked by limestone and grass walks flanked by walls and hedges. He incorporated ruined walls into the overall design, and built a rock garden on the steeper slope to the north-west of the house. Tipping also planted many trees and bushes, including a large circular arbour of yew on the highest terrace.
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.
