Nos 27 and 27a the Red Lion Hotel

The Red Lion Hotel, located at Nos 27 and 27A in Caistor, is a hotel and shop that dates back to the 17th century, with significant alterations made in 1835 and further changes in the 20th century. The building is constructed of rendered brick with stucco dressings and features a partially hipped slate roof supported by four brick ridge stacks.

The front of the building is three stories high and consists of five bays. It has a moulded cornice and a lead downpipe with a rainwater hopper. An off-centre doorway is sheltered by a porch supported by quarter engaged Tuscan columns, which hold up a frieze and entablature. The porch includes sidelights. To the left of the main entrance is a modern glazed doorway, while to the right is a modified 19th-century glazing bar sash window. There is also a basket carriage arch with plain capitals and a raised keystone.

On the first floor, there are five glazing bar sash windows, and on the second floor, there are five more similar windows. All the sashes feature narrow sills and shallow splayed stucco lintels. At the corner of High Street, there is a glazed door leading to the former 27B, and the corner itself has a four-light late 19th-century shop window with timber mullions that follows the curvature of the wall. The upper floors also have two similar windows, all adorned with shaped stucco keystones.

On High Street, there is an irregular single bay of windows; the ground floor has a plain window, the first floor features a small opening light, and the second floor has a blank opening. Further down High Street, there is an earlier attached block, likely from the 17th century, which consists of three irregular bays on the ground floor and two above, with two storeys and a steeply pitched pantiled gabled roof that has a raised gable and kneeler. This block includes a central axial stack and a first-floor band with a plain eaves band. The off-centre 19th-century four-panelled door is accompanied by two glazing bar sashes on the right, while the first floor has two smaller similar windows. At the rear, there is a large room on the first floor, dating from the late 18th century, which likely served as a former ballroom and retains some contemporary fittings.
