Landmarks
Siloa Chapel in Cwmefyn was built in 1866, as part of a series of churches founded by Azariah Shadrach in north Ceredigion in the Congregational Church of Salem Coedgruffydd. It was known locally as Capel Ucha (the Higher Chapel) to distinguish it from the Bethlehem Presbyterian chapel further down the village, known as Capel Isa (the Lower Chapel). The first minister of the church was Reverend W. Jansen Davies. The chapel is described by Coflein as having a "simple round-headed style, with a rendered exterior and slate roof with bracketed eaves". The chapel has a central double panelled door with a fanlight.

Cwmerfin lead mine is of prehistoric origin and was owned in the first half of the seventeenth century by Sir Hugh Myddelton (1560–1631) and Thomas Bushell (c. 1593–1674). As well as lead ore the mine produced zinc, copper and silver ore. The mine closed in 1889.
