Antrim Castle was erected in stages between 1613 and 1662. It was destroyed by fire in 1922 and finally demolished in the 1970s. All that remain are a slightly raised grassed platform as well as a freestanding Italian stair tower which was built in 1887 and a gatehouse, which was built around 1818 with twin neo-Tudor towers, with older connecting walls.
The gardens, originally dating from the 17th-century, are a popular tourist attraction. Jacobean-Revival outbuildings of coursed rubble basalt with sandstone dressings were built about 1840. The entrance gateway to the demesne has octagonal turrets. The stable block was later converted for use as a family residence and renamed Clotworthy House. This was acquired by Antrim Borough Council and converted for use as an Arts Centre in 1992.
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.
