Welsh Bicknor

Welsh Bicknor (Welsh: Llangystennin Garth Brenni) is an area in the far south of the English county of Herefordshire. Despite its name, it is not now in Wales, but it was historically a detached parish (exclave) of the county of Monmouthshire. It lies within a loop of the River Wye and covers 8,502 acres (13.3 sq mi).

As its name suggests, Welsh Bicknor has close ties with Wales, having been a detached parish of Monmouthshire, although adjacent to English Bicknor and Lydbrook, which are part of Gloucestershire.
