Watford Chapel

Watford Chapel is a symmetrical gable-entry chapel built in a simple classical style. The main structure dates to 1733, with alterations and an enlargement in 1842, 1877 and 1890. An inscription in the gable apex records these events: "WATFORD Congregational Church, Organised 1662, Building Effected 1733, Altered 1842 & 1877, Enlarged 1890." The chapel is rendered with a slate roof and plain barge boards. The front has three bays and is two storeys high, featuring round-headed openings to the upper storey, the central one being larger, and square-headed openings to the lower storey, all with hoodmoulds and stone sills. Central planked double doors have an overlight, flanked by single lights.

The rear east end features two tall round-headed windows with original wooden glazing bars, each containing two round-headed lights, a mullion and three transoms. A small lean-to is situated below. On the south side is a four-pane window set under a shallow segmental head. Adjoining the north side of the chapel is a small house, formerly for the minister, which is set back. It has a cement pan-tile roof, a yellow brick end stack, and is two storeys high with a single window. A planked door is on the right, and there are modern casement windows. Small square-headed windows are located in front of the house.

The entrance vestibule contains two panelled doors leading into the chapel. A window with coloured margin glazing is between the doors. A staircase to the left leads up to a raked gallery at the west end, supported by two narrow cast iron columns with five tiers of pews. The wooden gallery front has panels with diagonal planking. The chapel contains three banks of box pews with bench ends featuring circular finials. Wainscot panelling is present, along with a square-headed fireplace in the north wall. The roof structure is four-bay with plain collar trusses, boarded above, and incorporates hollow-moulded plaster coving. A reredos behind the pulpit takes the form of a blind round arch bearing the inscription 'Molwch yr Arglwdd'. A polygonal panelled pulpit is reached by stairs with turned balusters and square newel posts. A wood-panelled set fawr stands in front of a decorative organ, which was brought from America. A small wood-planked lobby is located in the southeast corner.

Numerous memorials are mounted on the walls, some of which were originally in the graveyard. One memorial is dedicated to Mary Richards (died 1767) and her husband William (died 1780) of Energlyn. A stone tablet with an arched head in the northeast corner commemorates Mary, wife of David Williams (died 1745), and her son. A wooden tablet is dedicated to Mary, daughter of David Williams (died 1837), who left £300 to the church.
