What is recorded here

Green Island tower house stands in Templetown, County Derry, a scheduled medieval ruin where stone walls still mark the edge of a forgotten residence. Its dual name, Castle of Anagh, hints at a family or claim now lost to time, yet the structure itself remains a clear anchor in the landscape. The tower likely watched the water, stored grain, or sheltered people during storms and conflicts. Its survival is not decoration but evidence that ordinary life once turned on the strength of its walls.

The official Northern Ireland record identifies this as TOWER-HOUSE: GREEN ISLAND or CASTLE OF ANAGH. Recorded period: MED/L.MED; MEDIEVAL; LATE-MED. Recorded protection: Scheduled. The official map point was placed at the centre of the recorded archaeological site from the source map reference.

The Tower-house on Green Island, also known as the Castle of Anagh, was built in the late medieval period, likely by a local Gaelic lord or Anglo-Norman family. It is remembered as a Scheduled Ancient Monument, reflecting its historical and archaeological significance in the region.
