Hamilton's Castle
Sir Frederick Hamilton arrived in north Leitrim in the 1620s as part of the Plantation, granted land that had belonged to the O'Rourke chieftains. He built a castle between 1634 and 1638 — stone walls, towers, a gated bawn. Hamilton became a byword for cruelty in his suppression of O'Rourke resistance. During the Confederate Wars of the 1640s the castle changed hands. In 1652 it was slighted — deliberately damaged to prevent refortification — by Royalist forces. The ruin stands in the town centre today: accessible, substantial, silent.
