Olderfleet Castle

Olderfleet Castle stands as a ruined four-storey towerhouse on Curran Point, situated just south of Larne Harbour in County Antrim, Northern Ireland. While the site name may derive from the Viking term Ulfrecksfiord, the current stone remains are widely believed to date from the sixteenth or early seventeenth century, possibly around 1612, rather than the original structure purportedly built by the Bissett family circa 1250. Historically known as Curran Castle or Coraine Castle on early maps, the site possesses a square footprint with walls only one metre thick. This specific architectural feature, combined with a lack of visible domestic amenities and the presence of gun loops in the basement, suggests the building may have functioned primarily as a fortified warehouse and watchtower rather than a traditional residential dwelling.

The location holds profound historical significance due to its strategic position overlooking Larne Lough. In 1315, Edward Bruce landed here with an army of 6,000 men, receiving a welcome from the local Bissett clan before proceeding with his campaign to conquer Ireland. Recognizing its military value, Queen Elizabeth I seized the castle for the Crown in 1569 and appointed Sir Moyses Hill as governor. The fortress later became a point of contention for the MacDonnells, who claimed it in 1597 before dismantling it the following year. After subsequent reconstruction, the property passed through the hands of the Chichester family and was eventually leased to private individuals in the nineteenth century.

Today, Olderfleet Castle exists as a State Care Historic Monument within the townland of Curran and Drumaliss. Although only partial ruins remain, the site is preserved as a key component of the local heritage trail. It serves as a tangible link to the region's turbulent past, marking the arrival of Scottish forces in the fourteenth century and reflecting the shifting powers of various clans and the English Crown throughout the subsequent centuries. The ruins continue to offer visitors insight into the defensive architecture and maritime history of the Larne area.
