Royal Arsenal Main Guardroom

The Royal Arsenal Main Guardroom is a disused guard house built in 1788, likely designed by James Wyatt and constructed by Isaac Ashton. It features yellow and red stock brick with limestone ashlar, ridge stacks, and a hipped slate roof. The building has a single-depth plan with a central archway and is two storeys high with a three-bay range. It includes a tetrastyle Doric portico that is one bay deep, adorned with a modillion cornice, leading to a similarly-sized flagged recess. The central doorway has double 6-light doors with raised panels, flanked by smaller doors to the guard houses on either side. The ground floor has segmental-arched tripartite 6/6-pane sash windows, while the first floor features gauged brick flat heads above 6/6-pane sashes with an ashlar cill band. The rear of the building has projecting wings on either side of the central entrance. Inside, there are cast-iron posts. Historically, it was used by the Army when it provided guards for the site and played an important role in the 18th-century Arsenal.
