Salvation Army Citadel

The Salvation Army Citadel is a Grade II* listed building located on Saddler Street in Durham, originally serving as assembly rooms and shops, and incorporating part of the North Gate of the Castle. The medieval gate is part of the structure, while the assembly rooms date from around 1800, with some alterations made to the ground floor. The ground floor is rendered, while the first floor features English bond brick with painted ashlar dressings. The roof is made of Welsh slate and includes brick chimneys.

On the left side, a shop from around 1900 has a recessed central door and shop windows with upper glazing bars. The central shop, dating from circa 1800, has a partly-glazed door with a 2-pane overlight to the left and a shop window with three rows of six panes to the right, topped by a patterned shallow segmental lunette. The entrance to the assembly rooms on the right features a many-panelled door set in a Greek Doric doorcase with columns and an entablature, flanked by narrow sash windows with projecting stone sills. The first floor has three large sash windows above the shops, each with wedge stone lintels and projecting stone sills, while a wide blank bay on the right is painted with "SALVATION ARMY" in an aedicule. The low-pitched roof has an end brick chimney.

Inside, there is a wide open-string stair with a swept wreath and curtail, and a round handrail supported by stick balusters. It is reported that fragments of the North Gate barbican can be found in the basement. The building is graded for its medieval parts.
