Ystradgynlais, Powys

Ystradgynlais is a town on the River Tawe in south west Powys; it is the second largest town in Powys, Wales. The town grew around the iron-making, coal-mining and watch-making industries. Up until the mid 18th century most of the Swansea Valley was thickly wooded and sparsely populated. The placename Ystradgynlais, meaning 'vale of the river Cynlais' - Cynlais may be a personal name, or derive from cyn ('chisel') and glais ('stream') - is first recorded in 1372.
