Fonmon Castle is a fortified medieval castle near the village of Fonmon in the Vale of Glamorgan. With its origins rooted in the 12th century it is today seen as a great architectural rarity, as it is one of few buildings that was drastically remodeled in the 18th century, but not Gothicized. The castle is believed to have remained under the ownership of just two families throughout its history; from Norman times, it was owned by the St Johns, and from 1656, by the descendants of Colonel Philip Jones.
Fonmon Castle is situated in extensive gardens and is constructed of local sourced stone, primarily limestone and blue lias rubble. There is one arched internal doorway which appears to be Sutton stone; but are covered in grey render which disguises much of the stonework. The roofs are of mixed slates with lead gutters and dressings.
The main building is of two and three storeys and castellated almost throughout. Apart from the south east corner tower, which is slightly higher, the walls are largely uniform in height.
In the grounds, to the south west of the house, there is an 18th-century stable which incorporates a late medieval barn. The south and east walls of the stable are castellated to impress those approaching from the south. The stable has a fine polygonal stone chimney, which is a rare surviving medieval find.
Further south is a battlemented watch tower of either 17th or 18th century design, thought to have been modeled on the one found at St Donat. It is believed the watch tower was constructed in two builds, and may have been founded on original ruined medieval stonework. Due to its time scale and features, it is assumed to have been constructed during the medievalizing improvements carried out by Robert Jones III.
Notable features inside the castle include the combined grand drawing room and library, designed by Thomas Stocking. Described by Newman as the 'glory of Fonmon', the library, running east to west is lit by two Venetian windows, a stone one to the west wall and a sashed timber oriel window to the east. The room is divided into three sections, the largest central, with square end bays with segmental arches. There are trophies of the chase in the spandrels of the arches and arabesques and wreaths adorn the flat of the ceiling with an Apollo head in a sunburst at its centre.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
