Crom Castle (Irish: Caisleán na Croime) is situated on the shores of the Upper Lough Erne in County Fermanagh, Northern Ireland, and set within a 1,900-acre (7.7 km2) estate.The Castle is built of grey stone with the main part of the building and wings being over two floors. The entrance is a battlemented tower with smaller towers to one side. The castle has formal gardens which reach out to the estate and parkland beyond. The ruins of Old Crom Castle can be found within the estate although now only part of the original walls, two towers and a ha-ha remain. There are also two of the oldest yew trees in Ireland inside the Old Castle grounds, believed to be over 800 years old.
