Builth Castle

Builth Castle (Welsh: Castell Llanfair-ym-Muallt) was a castle built under King Edward I, just outside Builth Wells, Powys, Wales. At one time it was an impressive stone-built castle but all the masonry has been removed over the years and all that remains are the mound on which it stood, the ditches and embankments.

Builth Castle was erected in 1277, the first castle to be built by King Edward I in Wales. The site chosen was a pre-existing motte-and-bailey castle with a motte surrounded by two baileys, all surrounded by a further boundary wall. This older castle had already changed hands several times as the Normans and Welsh fought for supremacy in these parts, and the small town of Builth had sprung up nearby. In 1260 the old castle was taken and largely destroyed by Llywelyn ap Gruffudd. It is not clear how much of the original structure was still there when Edward I started building his stone castle. Construction started in May 1277, and continued until August 1282, when the castle was left unfinished for lack of money.

This was probably because Llywelyn ap Gruffudd had been killed and Edward had changed his priorities because he wanted to concentrate on his invasion of Gwynedd. As at Flint Castle begun at the same time, construction began with an enclosure of the site by a wooden palisade, in the case of Builth of some 270 yards in length. Records show that the total cost of the castle was £1,666, a comparatively modest sum because the earthworks were already present on the site.

The castle was besieged in 1294 during the revolt of Madog ap Llywelyn. On 7 February 1301, Edward I gave Builth Castle to his son, Edward. Between 1310 and 1315, a local magnate - Roger Mortimer - served Edward as castellan of Builth. When the latter Edward succeeded his father as king, he gifted the Castle to his wife, Isabella; in turn, with Edward's consent, Isabella rented the castle back to Roger Mortimer, for 170 marks per half-year (due at Michaelmas and Easter). Mortimer, a man with an increasingly powerful hold over Isabella (who eventually became his lover), subsequently obtained an agreement that the castle would become his outright when Isabella died.

Isabella and Mortimer executed a coup against Edward, eventually resulting in Edward's ignominious death.
