Castle Caulfield is a large ruined house situated in Castlecaulfield, Northern Ireland. The house was built by Sir Toby Caulfeild between 1611 and 1619. He was granted 1000 acres during the Ulster Plantation. This land was previously owned by the O'Donnelly family, who were closely connected to the O'Neill clan in Dungannon. The O'Donnelly fort was a few miles West of the castle. There are substantial remains. The gatehouse was rebuilt at a later date, although one of the doorways may be reused.
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.
