Pen-y-garn is a small village in the Tirymynach district of Ceredigion, Wales, approximately 4 miles (6 km) north-east of Aberystwyth.

[3] Along with the hamlet of Rhydypennau, Pen-y-garn is now often considered to be part of the neighbouring larger village of Bow Street.

[5] But his claims with regard to this have not been substantiated, and appear to be based solely on the name of the farm and its position, as well as a misplaced belief that the first element of this was the Welsh word 'caer' meaning 'a fort'.

Rather it was actually some distance down the slopes of the hill on the north side of the Aberystwyth to Machynlleth road, near to Bow Street brook, and its name is probably connected with this location instead of that of the current farmhouse.

Evan Richardson, teacher John Elias and Hugh Owen were the first Nonconformists or dissenters to preach in the area in about 1780.
