Entrance range of Conwy Public Library

The entrance range of Conwy Public Library is a Gothic style, two-storey structure that was originally part of the former town hall. It is built of snecked rubble with freestone dressings and quoins, topped with a steep hipped slate roof that features a moulded stone cornice and prominent ironwork cresting. The Castle Street side has angle buttresses on the lower storey. The entrance consists of a wide pointed arch with a hood mould, which has modern glazed doors and panels inserted. To the right of the entrance is a two-light mullioned window with round-headed lights, and to the left is a similar single-light window. On the upper storey, there is a five-light mullioned and transomed window with round-headed lights, the central light of which is raised and also has a hood mould. A central coped dormer features a boarded-up round window.

A square corner turret on the first floor is corbelled out on a freestone arcaded frieze, with additional corbels at the angles below a string course that runs continuously with the eaves cornice of the main building. The turret has narrow louvres beneath a steep swept pyramidal roof, and a string course above the adjacent window on the Castle Street elevation acts as a hood mould.

On the High Street elevation, there is a single-light window on the lower storey, two similar windows on the first floor, and a larger two-light mullioned window on the upper left. An angle buttress to the left supports a corbelled former first-floor stack that has been reduced to eaves level. Further back, there is a six-bay range that remains in its original form on the lower storey, while the upper storey has been replaced with concrete.

Inside, the entrance hall features two double-chamfered arches, with joist-beam ceilings supported by ovolo-moulded cross beams. The interior has otherwise been modernised.
