Capel Dewi, Faenor

Capel Dewi is a hamlet in Ceredigion, Wales, approximately 3.5 mi east of Aberystwyth. It is one of two settlements called Capel Dewi in the county, the other being Capel Dewi near Llandysul.

The majority of Capel Dewi lies south of the River Peithyll, a tributary of the Afon Clarach. One of the more unusual features of the hamlet is the nearby LIDAR system, which is run by the University of Manchester.
