Description
Dean's Yard is a Grade I listed school house with an archway leading to Little Dean's Yard. It has origins from the late 14th century and is part of the west range of the Abbey buildings, originally serving as the Bailiff's Guest House. The building was taken over by the Grammar School in 1461 and underwent significant alterations and rebuilding in 1886, likely by T.G. Jackson. Constructed from stone rubble with ashlar dressings and a slate roof, it features a Tudor-Gothic style from the 1886 renovation.
The structure has three storeys and is eight windows wide, with a broader and taller entrance "tower" bay on the left. There is a late 14th-century archway to the left that has a tierceron vault, leading into Little Dean's Yard. To the right of the archway is a pointed arched doorway that has been altered into a two-light window. The building includes two and three-light mullioned casement windows with cusped heads. The "tower" section features a first-floor oriel window with a pierced-work parapet. The elevation is topped with a crenellated parapet, and the taller section of the "tower" has a polygonal turret at the corner. The rear elevation facing Little Dean's Yard exhibits similar architectural features.
