That part of the Black Mountain which is within the parish forms the loftiest elevation in the county . . . The church, dedicated to St. Simon and St. Jude, is inconveniently situated at the eastern extremity of the parish, at the foot of the Black Mountain . . . A fair is held annually in the village on the 10th of October. The living is annexed to the vicarage of Llangadock. . . There is a meeting-house for Calvinistic Methodists, who have also five Sunday schools, in which 620 males and females are taught gratuitously; and there is a day school, in which 60 children are instructed at the expense of their parents."
