The Pontypridd Museum (formerly Tabernacle Baptist Chapel)

In a simple classical style of coursed, rock-faced stone with freestone dressings and quoins, and slate roof with ventilators. The symmetrical, 3-bay front has round-headed windows with bracket sills, and 2-light cast iron frames of 1910 with horizontal glazing bars and diamond paned heads. The gabled porch in the wider central bay is in neo-Baroque style. It has a gated entrance beneath a round arch with keystone. Rusticated pilasters are inscribed with names of former ministers, above which are entablature swags. Above the porch the central bay has a pair of windows, while the outer bays have single windows. A string course is between the storeys. A bracket cornice defines a pediment, within which is a round-headed recess with bracket sill containing a date stone. Quoins below and string course between floors.

The 3-window side walls have windows similar to the front. On the R side is a round-headed basement doorway with replaced door, and 3 basement windows similar to the remainder except one replaced.

The interior is converted to exhibition use. It retains its 3-sided gallery with cast iron columns and boarded panel front. The ceiling has a coved cornice and is divided into 4 quadrants with diagonal ribs of painted foliage and boarded bands, and has a central octagon panel. A swept semi-circular arch behind the pulpit frames the organ installed in 1910. The pulpit has a panelled front with flanking balustrades and steps.
