Corinium Museum and Attached Gateway

The Corinium Museum, originally a house, dates from the mid-18th century and has undergone later alterations. It is constructed of limestone ashlar with coursed rubble on the right side and coursed squared limestone on the left. The building features a stone slate hipped parapeted roof, with a concrete tile covering on the rear range to the left. Rebuilt brick stacks are located on gablets at both ends of the front range, and there is a brick stack on the left end of the rear range.

This 7-bay Palladian villa has a central section of 3 bays that projects forward and is topped with a pediment. The building is three stories high and has a 7-window arrangement. The first floor includes seven 6/6-pane horned sash windows, with three in the center set in moulded stone architraves featuring keyed lintels and stone cills, while the left and right windows are in plain reveals with stone cills. The second floor has seven similar 3/3-pane sash windows. On the ground floor, there are six 19th-century 2/2-pane horned sash windows in plain reveals with stone cills. The central entrance features a Doric doorcase with an open pediment, which has been infilled with 20th-century glazing.

Additional architectural details include a shallow plinth, chamfered rustication on the ground floor that forms voussoirs over the window heads, and band courses above the ground and first floors. The building is topped with a bracketed eaves cornice and a parapet with a blocking course. The entrance is now located in a 20th-century addition at the rear left, accessed through a round-headed opening in a 19th-century screen wall that has a moulded architrave, impost bands, and a bracket keystone. This entrance features an aedicule with two Ionic columns, a full entablature, and a dentil cornice, along with a blocking course and a pair of 19th/20th-century iron gates. The interior has been significantly altered in the 20th century for museum purposes.
