First built in 1742, possibly to the designs of William Edwards who built Libanus in Morriston in 1782 (NPRN 13492), Groeswen Independent Chapel was the first meeting place in Wales of the Calvinistic Methodists. The chapel was enlarged/rebuilt in 1766, enlarged further in 1830 to the design of architect William Lewis and the burial ground extended in 1865. The present chapel is built in the Sub-Classical style with two storeys, a gable-entry plan and a large arch in the facade. Groeswen is now Grade 2 Listed for its historical association with a number of religious leaders and their burial in the graveyard.
