Description

Coates Castle is an early 19th-century castellated mansion, built by John King and now converted into flats. The main block is two storeys high with five windows. The exterior is faced with Roman cement. The east front features a projecting central portion with a castellated gable, containing a cartouche and flanked by buttresses. A four-centred arched doorway is positioned centrally. Buttresses also define the flanking window bays. To the north of the main block is a simpler section with a plain gable and an octagonal turret, the top storey of which has been removed. A similar three-storey turret is set back at the south end. Originally, there was a further wing to the north, but this was demolished. A long, single-storey projecting wing with four windows and a castellated parapet extends to the north-east, backing onto the stable yard. Finally, to the east, there’s a three-storey tower with one window, followed by a two-storey section with two windows.
