What is recorded here

Syonan Castle is a four-storey limestone tower built before 1566 for the McGeoghegan clan, standing on a small ridge in County Westmeath. Its walls still hold arrow loops, fireplaces and a blocked spiral staircase, while scattered quoin stones mark the corners where time has loosened the build. The castle remains vivid because it is not a ruin reduced to powder; it is a inhabited-shaped fortress that kept its form through centuries of Irish weather.
