Llantrisant

Llantrisant is a town in the county borough of Rhondda Cynon Taf in Wales, within the historic county boundaries of Glamorgan, Wales, lying on the River Ely and the Afon Clun. The town's name translates as The Parish of the Three Saints. The three saints in question are St Illtyd, St Gwynno and St Dyfodwg. Llantrisant is a hilltop settlement, at an altitude of 174 m (565 ft) above sea level. A settlement has existed on this site from at least the beginning of the 6th century, when the poet Aneurin wrote of 'the white houses of Glamorgan' when referring to Llantrisant. It was seized around 1246 by Richard de Clare who built Llantrisant Castle. It is thought that de Clare established the borough of Llantrisant though the exact charter occurred in 1346.
