The story of Limavady Motte
The high bluff above the Roe gorge has been a stronghold for centuries. The O'Cahans ruled this area from the 14th century, and the motte marks the traditional site of their castle, set in a position that controlled the river crossing and the valley below.
Limavady takes its name from this place. 'Léim an Mhadaidh', the leap of the dog, recalls the O'Cahan wolfhound said to have leapt the gorge at the nearby Dogleap to carry warning to its master. The town grew from the settlement around the castle.
O'Cahan power ended in the early 17th century. The last chieftain, Donal Ballagh O'Cahan, surrendered to Sir Henry Docwra in 1602 and later died a prisoner in the Tower of London in 1628. In 1610 Sir Thomas Phillips was granted land at Limavady that included an O'Cahan castle; a Thomas Raven map of 1622 records a tower-house here, which Phillips adapted with an artillery fort and a three-part walled garden behind it.
Little of that castle survives today. What remains is a small grassy mound on its defensive position high above the River Roe, now part of Roe Valley Country Park and in the care of the Department for Communities.
