Alnwick Abbey Gatehouse

The Alnwick Abbey Gatehouse is a Grade I listed building that dates from the late 14th century, with some minor alterations and restorations from the late 18th and 19th centuries. Constructed of ashlar stone and topped with a Lakeland slate roof, this rectangular two-storey structure features projecting, taller angle turrets and is designed in the Perpendicular style.

On the north front, which was formerly external, there are Gothick panelled double doors set beneath a moulded segmental arch. Flanking the doors are small recesses, with two niches above, the lower of which contains a worn statue. The gatehouse is crowned with a machicolated parapet adorned with shields and moulded crenellations. The flanking turrets, which are corbelled out at different levels, have small loops, some featuring trefoiled ogee heads. To the right, there is a single-storey block, likely post-medieval, which also has two small loops.

The south front mirrors the north with a similar arch and features a two-light transomed window above. The turrets have flat-pointed doorways, one of which is blocked. The left turret includes a two-light transomed window with cusped heads and metal lattice casements.

On the east side, the centre is deeply recessed and features a blocked four-centred arch beneath a canopied niche, with transomed and traceried two-light windows above and in the right turret. The turrets and machicolated parapet display carved hoodmould stops and heraldic designs. The west side reveals small loops and a corbelled-out garderobe beneath the parapet.

Inside, the gate passage is covered by a segmental barrel vault. A straight mural stair leads to the first floor in the west wall, while a full-height newel stair is located in the south-east turret. There are four-centred arched doorways leading to the stairs and turret chambers.

Historically, the abbey was founded in 1147 by Eustace Fitz-John and was renowned for its relics, including the foot of Simon de Montfort and the chalice of St. Thomas of Canterbury. The main buildings of the abbey were situated to the south of the gatehouse; although excavations in 1884 outlined the plan, it is now only faintly traceable.
