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 Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
