Brynhenllan Methodist Chapel was built in 1769 and rebuilt in 1799. The present structure and interior date from a second rebuild in 1842, constructed in the later Vernacular style with a long-wall entry plan and two storeys. Brynhenllan is now Grade 2* Listed for it's very fine 1842 interior, including a five sided gallery on marbled timber columns, rare in south west Wales.
