A site of interest in Ventry parish is Rahinnane Castle, which was the residence of the Knight of Kerry. The Knight of Kerry lived there until Cromwellian times. The castle was built on the site of an old ringfort. The ringfort was built up and a second added with walls of six metres (20 feet), giving the appearance that there may have been a moat, although there never was one. Rahinnane Castle still has its very tiny, narrow, stone stairs, from the first to second floors, which can be carefully climbed.
