Carrigaphooca Castle ( meaning "castle on the rock of the fairy"; the word púca translates as ghost or fairy) is a ruined five storey rectangular tower house situated on a steep-sided rock overlooking the River Sullane. It is located 6 km west of Macroom, County Cork, Ireland, in an area once known as Gleann na n-Dearg ("valley of the reds"). The tower dominates the landscape of Lissacresig (Fairyland) in Clondrohid, and Lower Shanballyshane, in Kilnamartyra. Carrigaphooca is made of sandstone and limestone and was built as a defensive tower by the MacCarthys of Muskerry in the early 15th century. Read more on Wikipedia
