The chapel's foundation dates to the 17th century and the structure was rebuilt in 1841, then again in 1892.

[2] Cadw, the historic environment service of the Welsh Government, listed the chapel as a Grade II* historic building in 1976 for its "unusual porch" and "elaborate and fine interior".

[3] The present building dates back to 1841 and was re-modelled by Owen Morris Roberts in 1892.

[1] Particularly notable is the beautiful woodwork of the gallery fronts and pulpit.

The vestry contains memorial plaques from the former Glamorgan Street Congregational Church.
