==History== The place-name 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. In the 1600s there were only a couple of houses by the church and a pub (now the rectory). In 1801 there were only 993 residents in the town living in only 196 houses. The first documented written evidence of iron working in the area was at Ynyscedwyn and is of a deed of release dated 1729. By 1750 there were seven furnaces in south Wales, one of which was at Ynyscedwyn.
