The Subdeanery and East Midlands Tourist Board Offices

The Subdeanery and East Midlands Tourist Board Offices, located in Minster Yard, Lincoln, comprise a building with origins in the 13th and 14th centuries, with additions from the 17th century, and substantial remodelling and extension in 1827. A refronting occurred in 1873, undertaken by J. L. Pearson. The site contains significant archaeological remains from the Roman period, including a hypocaust and mosaic pavement, which remain in situ.

The building is constructed of dressed stone and brick, with a stuccoed east front, ashlar dressings, and plain tile roofs, punctuated by four gable and single ridge and side wall stacks. The exterior features a sill band, two string courses, an eaves band, coped parapets, and gables to the north and east fronts. It has an L-shaped plan and is two and three storeys high, with three bays on each visible front.

The north front incorporates steps leading to a moulded four-centred arched doorway with sidelights and overlight. Above the doorway is a four-light stone mullioned cross casement window. To the left is a square bay window with similar four-light windows on both floors. The east front features a wooden doorcase with a recessed six-panel door and a glazing bar sash window to the right. A square stair tower with a parapet is also present, with single-light windows on the lower floors and a cross casement above. The south side displays two fronts and has glazing bar casement windows in each bay.

Internally, No. 18A has a partly panelled entrance hall dating to the late 17th century, notable for its wooden fireplace, overmantel, and moulded beams. A first-floor room exhibits similar fielded panelling. The basement reveals a section of Roman tessellated pavement, approximately 1 by 1.5 metres, a medieval cistern, and a Roman hypocaust. The hypocaust, approximately 10 metres by 5 metres, is accessible via a stone winder stair within a stone-lined round arched stairwell. At the foot of the stairs, a segment arched recess faces a round arched brick firehole. The hypocaust is supported by square brick columns carrying a terracotta floor.
