Olderfleet Castle is a four-storey towerhouse, the remains of which stand on Curran Point to the south of Larne Harbour.
The original towerhouse was possibly built by the Scoto-Irish Bissett family of Glenarm around 1250, although these remains are actually thought to be those of Curran Castle, a towerhouse built in the sixteenth-century. On a 1610 map it was called Coraine Castle.
In 1315 Edward Bruce landed here with his 6000 strong army en route to conquer Ireland, with a welcome from the Bissetts. Queen Elizabeth I considered the castle of such strategic importance that it was seized for the crown and Sir Moyses Hill appointed its governor in 1569. In 1597 the castle was claimed by the MacDonnells and in 1598 it was dismantled.
The present castle was probably built about 1612. In 1621 it was granted to Sir Arthur Chichester and remained in that family until leased to William Agnew in 1823. James Chaine purchased the lease in 1865. In 1938 it was taken into State Care.
What remains of the four-storey towerhouse is part of the tower with pairs of gun loops in the basement. The square remains show that it only had 1 metre thick walls and it is without visible domestic features, which means that it could have been built as a fortified warehouse and watchtower.
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.
