Sketrick Castle castle dates from the late 12th century. In the 14th century it was acquired by Sir Robert Savage. The Annals of the Four Masters record the capture of the castle in 1470 by an army led by the O'Neill to assist the MacQuillans. They took the castle and it was given to MacQuillan for safe keeping. It was intact until 1896 when a storm demolished much of it.
Sketrick Castle was four storeys high, with a boat bay and a stone subterranean passage discovered in 1957. It had four chambers at ground level, the largest with a vault constructed on wicker centring, as well as two brick-lined recesses, probably ovens. It has lintels running under the bawn wall to a chamber with a corbel over a fresh water spring. Parts of the bawn wall still survive to the north and east of the castle.
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.
