What is recorded here
Mount Alexander Castle left no visible ruin, only a hidden fortification site buried beneath the ground of County Down. Its age remains unknown, but the name suggests people once built a defensible home on elevated land before forgetting or losing it. The hill may still hold compacted walls, broken chambers or abandoned rooms that no longer appear on any map.
The official Northern Ireland record identifies this as FORTIFICATION (site of): MOUNT ALEXANDER CASTLE. Recorded period: UNCERTAIN. The official map point was placed at the centre of the recorded archaeological site from the source map reference.
Built in the 17th century, Mount Alexander Castle was constructed by the Alexander family, likely as a defensive stronghold during the turbulent period of Confederate Wars in Ireland. It is remembered for its historical association with local resistance and as an example of early modern defensive architecture in the region.
The monument record does not grant public access. Check the route and ask the landowner before entering private land.
