Builth Wells
Builth Wells is a market community and area in the region of Powys as well as historic region of Brecknockshire (Breconshire), mid Wales, existing at the confluence of rivers Wye as well as Irfon, in the Welsh (or upper) part of the Wye Valley. It has a population of 2,568. A lot of the community's structures, including the 1876 Market Hall, were developed from stone from Llanelwedd Quarry. Much of the encountering as well as various other dressed stone used in the building and construction of the Elan Valley dams was also quarried right here. The quarry produced the first occurrence of laumontite in Wales. The quarry is currently run by Hanson Aggregates. Builth is a longstanding anglicization of the Old Welsh Buellt/Buallt which incorporates bu be, equivalent to some Middle English orthography), meaning "ox" with gellt (later gwellt), implying "lea or leas"; the very same kind is used despite gender of the pet. The town included "Wells" in the 19th century when its springtimes were advertised as a site visitor attraction. Its modern Welsh name Llanfair-ym-Muallt indicates "Saint Mary in Ox Leas".
