Twr Mihangel (formerly known as Treturret), Crucorney is a 17th century house with a look-out tower possibly dating from the late 16th century. The building is roughly squared with coursed red sandstone rubble and stone tile roofs. There is a two storey three bay cottage with a gabled porch with heavy studded plank door in a chamfered frame. To the right the house is extended by a further bay to join the octagonal two storey look-out tower. This has 2-light small paned casement wndows with dripmoulds on every other face, castellated parapet, tall castellated chimney. On the garden elevation the tower is joined to the house by a castellated wall. Now in use as holiday accommodation.
