BUILTH WELLS

'Builth Wells' () is a town in Powys, traditional county of Brecknockshire, mid Wales, lying on the River Wye. Builth Wells is named after and is the centre of the cantref and once-time Kingdom of Builth, a minor Welsh sub-state during the dark ages.
Builth Wells grew as a market town and spa, and is known as the location of the Royal Welsh Showground, home to the Royal Welsh Show (although the showground is actually over the river Wye in Llanelwedd, Radnorshire).
The town in served by Builth Road railway station on the Heart of Wales Line, which is located just over a mile to the north, having lost its more central railway station on the Mid Wales Railway in the 1960s. One of the main Wales north-south trunk roads, the A483 passes the town, using that former railway route. A dedicated cycle route linking the town with Swansea (NCR 43) has been proposed and a 13 mile section of the route from Swansea has already been developed.
It was probably at Cilmeri - a village close to Builth Wells - that Llywelyn ap Gruffudd ''Ein Llew Olaf'' was ambushed and killed as he tried to rally the men of the lordship of Builth in December 1282.
Builth Wells has the distinction of having the only post box in the United Kingdom bearing the cypher of King Edward VIII, the uncrowned king whose abdication in 1936 caused a constitutional crisis.
