The Baptist Chapel in Llanidloes was designed by Richard Owen of Liverpool, and opened in 1877 on the site of a smaller church dating from 1824. The foundation stones are dated August 2nd 1876. The chapel has an impressive two storey facade, characterised by its giant order pilasters, and round-headed arched windows. The front of the building has paired semi-circular headed doorways with classical ornament, below a central three-light window, and flanked by full height recesses, with arched sash windows above, and square headed below. The side elevations each have four bays with windows in a corresponding style. The cross hipped roof is of slate with some fishscale cresting and finials. The chapel remains in use, and was sympathetically renovated in 1990. The original architect's ground plan for the chapel was discovered by chance in the basement of a shop in the town, and is now on display in the vestibule. Llanidloes Baptist is now Grade 2 Listed.
