Features
East of the village, the River Teifi emerges from a deep ravine over a ledge that produces a spectacular waterfall when the river is in full spate and this attracts many visitors throughout the year. A dramatic painting of the falls was made by Frank Miles and is now at Nottingham City Museum. Miles's father inherited Cardigan Priory from his father, Philip John Miles, but lived in Nottinghamshire as Rector of Bingham. A dominant feature of the village is Cenarth Bridge over the Teifi west of the falls; the bridge was built in 1787 by William Edwards of Eglwysilan and his son David. The bridge features their trademark series of circular holes (perforated spandrels that allow the weight of the structure to be reduced without losing strength. The bridge is a Grade II*-listed structure and is partly in Carmarthenshire and partly in Ceredigion. Other visitor attractions are a seventeenth-century flour mill and coracle museum. The village is home to the National Coracle Centre.
Worship
The parish church is dedicated to the localsaint, St Llawddog. Although the present building is relatively modern, it is on an important ancient site, and was the "bishop house" of the cantref of Emlyn.
