Rhydwyn's congregation, or cause, was established in 1791 and the chapel was first built in the period between 1800 and 1810. It was rebuilt in 1814 and again in 1842 (according to a plaque re-set in the wall). Rhydwyn was rebuilt again in 1914 (according to a plaque on the present south-eastern show-front). The current form is a hipped-roof 'box' and its walls probably date substantially from the rebuilding of 1842. The side-wall, facing away from the road and onto the extensive burial-ground, has domestic-style windows which probably date from the chapel of 1842. In 1914 the more visible walls of the chapel seem to have been given a more gothic guise with lancet narrow gothic windows and a three-light perpendicular traceried window over the central south-eastern entrance front and porches. A structure alongside the stream on the south-eastern edge of the burial-ground may have been a Baptismal tank. This chapel is of interest for the way it illustrates how congregations only tended to embellish those sides of the chapel most visible to the general population.
