RHANDIR-ABBOT, a hamlet, in the parish of LLANVAIR-AR-Y-BRIN, higher division of the hundred of PERVETH, county of CARMARTHEN, SOUTH WALES, 7 miles (N.) from Llandovery; containing 594 inhabitants. It is situated on the eastern bank of the Towy, and at the foot of a mountain in which are extensive lead-mines belonging to Earl Cawdor, the working of which is now discontinued. The chapel of Nant-y-Bai is in this hamlet, having been re-erected here, instead of at Ystrad-Fin, where the original building stood. The living is a perpetual curacy, endowed with £200 private benefaction, and £1000 royal bounty, and in the patronage of Earl Cawdor. A day school, containing 25 children, is supported partly by his lordship, who allows the teacher £5 per annum, and partly by the parents; and there are also three Sanday schools, in which about 120 males and females are gratuitously taught. Nearly opposite Earl Cawdor's mansion of Nant-y-Mwyn, where the banks of the river are somewhat precipitous, is a picturesque foot bridge across the Towy, leading to Pwll Pmdog.
