Coolamber Hall House
Just outside Lisryan, at Coolamber, stands the ruin of an Anglo-Norman hall house dating from the early thirteenth century - a rectangular two-storey block with a large first-floor hall and a separate four-storey service tower at the south-east corner, a late-medieval church to its north-west. The remains of a barrel vault survive at the north end of the ground floor; fireplaces and ogee-arched windows were cut into it in the sixteenth century. It sits on a semi-circular platform once enclosed by stone walls, on what was the boundary of the English Pale in the seventeenth century. It may have been the residence of Thomas Nugent, a commissioner of the Plantation of Longford under James I around 1620. It was besieged by Oliver Cromwell during his invasion of Ireland after 1649. It stands next to the road, highly visible, but on private property and not open to the public - this is a look-from-the-verge ruin, not a managed site.
