White Castle

Also known as, or recorded in historical documents as; Llantilio Castle; Blanc Castle

In the community of Llantilio Crossenny.
In the historic county of Monmouthshire (Modern authority of Monmouthshire, preserved county of Gwent).

Originally a single ward castle with a crescent shaped barbican surrounded by a formidable wet most. The ward was built in stone with a square keep in C12. The keep was demolished in C13 and the curtain wall given four round towers and a twin tower gatehouse. The barbican appears to have been abandoned as part of this rebuilding as a very large but weakly defended outer ward was built to the north. A strongly fortified oval enclosure, c.50m by 38m, defined by a C12 curtain with C13 towers, having a crescentic hornwork to the S, both contained in a broad moat. From the NW to the SE is an outer, ditched and scarped enclosure, of which the NW part has C13 walls and towers. The whole work is c.175m by 220m. Work is mentioned, 1161-2 and 1184-7, and thought to have occurred c.1257-77. The castle was described as roofless and derelict in C16. A long, round-angled, field enclosure, c.165m NNW-SSE by 26m, adjoining the castle earthworks on the SW, may be associated with the castle. The castle was held in common with Grosmont and Skenfrith. The C13 work has arrow loops of interesting and ?unique design. Possibly the large castle of 'Guyn' (Gwyn) in Leland's list of castles in Herefordshire.
