Seion Independent Chapel was built in 1775 and rebuilt three times, in 1804, 1835 and 1859. The present chapel, dated 1859, is built in the Simple Round-Headed style of the long-wall entry type and was renovated in 1889. Seion is now Grade 2 listed as a well-preserved late Georgian chapel in an attractive village setting.
