The Old Post Office and area balustrade

The Old Post Office is a former post office building dating from 1871 to 1874, designed by James Williams. It is constructed of sandstone ashlar with a visible roof. The building is in a Classical style.

The building is four storeys high and comprises three bays. It features two superimposed Giant Orders – Roman Doric on the two lower floors and Corinthian above. A fluted band runs along the ground floor. A central porch is set back within a surround and contains a recessed double door with an overlight, flanked by narrow windows. A tripartite sash window sits above. Sashes are located in the outer bays, flanked by pilasters. The first-floor entablature has a triglyph and guttae frieze. The sash windows are set within architraves; those on the second floor have apron balustrades and bracketed pediments, with the central segmental one resting on Ionic pilasters. A patterned sill band is present on the third floor. Rusticated quoins and a top entablature featuring a central panel reading "POST OFFICE" in low relief are also visible. The building has a wide dentilled eaves cornice. One bay is set back on the right-hand side, and is of a plainer style. A stone area balustrade with chamfered moulded coping runs alongside the building.

Historically, post offices were targeted by suffragettes as part of a campaign of disruption. In October 1909, suffragettes Kitty Marion and Dorothy Pethick entered the post office with stones hidden in their hand muffs, smashed the windows, and ensured no one was hurt by glass, before being arrested and imprisoned.

The listing was amended in 2018 to mark the centenary commemorations of the 1918 Representation of the People Act.
