Builth Wells
Builth Wells is a market community and area in the county of Powys as well as historic county of Brecknockshire (Breconshire), mid Wales, existing at the assemblage of rivers Wye and Irfon, in the Welsh (or top) part of the Wye Valley. It has a population of 2,568. A number of the town's structures, consisting of the 1876 Market Hall, were constructed from stone from Llanelwedd Quarry. Much of the facing and various other dressed rock used in the building of the Elan Valley dams was also quarried right here. The quarry generated the first occurrence of laumontite in Wales. The quarry is presently operated by Hanson Aggregates. Builth is a longstanding anglicization of the Old Welsh Buellt/Buallt which integrates bu be, comparable to some Middle English orthography), suggesting "ox" with gellt (later gwellt), meaning "lea or leas"; the same form is utilized regardless of sex of the pet. The town added "Wells" in the 19th century when its springtimes were advertised as a visitor destination. Its modern-day Welsh name Llanfair-ym-Muallt implies "Saint Mary in Ox Leas".
