Head Post Office

The Head Post Office, located on Wallgate in Wigan, was built in 1884 and has undergone slight alterations externally. It is constructed of pink Triassic sandstone ashlar at ground level, with red brick in a Flemish bond pattern and sandstone dressings on the upper floors, topped with a hipped slate roof. There are 20th-century extensions to the rear. The building is designed in a Free Renaissance style, combining elements of an Italian palazzo with Queen Anne Revival influences.

The building is three stories high with an attic, featuring a three-by-one window arrangement across two bays of unequal width. Architectural details include a molded egg-and-dart cornice at ground floor level, a sill band to the second floor, a plain frieze, a dentilled cornice, and an attic gable over the wider first bay. A doorway is located on the left side, framed by fluted pilasters, an architrave, a raised panel inscribed "1884", and a swan-neck pediment with swag embellishments. To the right of the doorway is a large elliptical-headed window, also with fluted pilasters. A two-light window is situated in the second bay. The upper floors feature tall windows in the first bay and pilastered tripartite windows in the second bay, all with molded architraves. The first-floor windows are sash windows without glazing bars, equipped with tilting casement openings at the top. The second-floor windows are also sash windows, predominantly with glazing bars in the upper portions. The attic gable contains an oculus set within a voluted stone arch and is finished with gable coping and a finial.

A three-story rear extension was added in 1895 by WEV Crompton of Wigan and is faced with glazed brick and terracotta dressings. This extension's ground floor features enriched door and window openings, while the upper two stories have sash windows with glazing bars.

The interior has been altered. The building contributes significantly to the architectural character of the area and has group value alongside the nearby K6 Telephone Kiosks, the Bees Knees Public House, No. 22, Nos 12-20, Nos 6, 8, and 10, the Church of All Saints, and the War Memorial.
