Rhydygwain Unitarian Chapel was built in 1808, and then rebuilt in 1848 and restored in 1873. The present chapel, dated 1873, is built in the Simple Round-Headed style of the long-wall entry type. Rhydywain is now Grade 2 listed as a well-preserved early nineteenth century chapel with a good interior of 1873 and an unspoilt attached chapel house.
