The Hall (formerly Glyncorrwg Workmen's Institute and Memorial Hall)

The Hall, formerly Glyncorrwg Workmen’s Institute and Memorial Hall, is an institute of the 18th century, built on a steep slope. The main, single-storey street-facing front forms the upper storey of the building. The front elevation is in a classical style, featuring eight symmetrical but unequal bays constructed of rock-faced stone with rusticated pilasters to the angles and the bays set back from the ends where the doorways are located. The outer bays are slightly set back. The windows are 12-pane horned sashes. The doorways have Doric surrounds, above which are lunettes and open pediments breaking through the parapet. Above the windows is a moulded cornice and parapet, to the centre of which is a panel with lettering in relief reading 'Glyncorrwg Workmen's Institute and Memorial Hall'. Below street level, the lower storey has openings in brick surrounds conforming to the bay structure above, and its doorways are accessed by steps against the side walls leading to a narrow pavement.

Set back behind the parapet is a double-height auditorium under a hipped slate roof with a central cupola. The left-hand side wall is cement rendered and has four bays offset to the left, with replacement windows. The right-hand side wall has a sash window to the left in the upper storey, similar to the front, and a replacement window below, with smaller service windows further to the right. The rear wall has two tiers of windows to the double-height auditorium, each with six windows, and a doorway to the centre at the lower level. The lower storey has seven replacement windows, with a window to the left between the lower and middle storeys. The basement has a blocked segmental-headed window to the left in a brick surround and a segmental-headed doorway to the right with a replaced door.

The main entrance is through the left-hand doorway, opening onto a landing and an open-well stair with plain newels and balusters leading to the lower storeys. The landing has a cornice with egg and dart moulding and a later partition. The front centre room was originally the reading room. Behind this is the double-height cinema or auditorium, which, despite being poorly preserved, retains a segmental plaster vault with ceiling roses, a classicising cornice, and architrave to the stage. The lower storey, which originally housed a ballroom, has been modernised.
