Seion Independent Chapel was built in 1851 and renewed as Capel y Fron in 1881. The present chapel, dated 1881, is built in the Sub-Classical style with a gable-entry plan. The pedimented, symmetrical and rendered facade has a central doorway with tripartite windows over and tall flanking margin-paned windows, all round-headed.
