Heiferlaw Tower

Heiferlaw Tower is a lookout tower for Alnwick Abbey, dating from 1470 to 1489, as indicated by its heraldry. The tower is constructed from large squared stone and is currently roofless. It has a rectangular shape, measuring 8.76 by 7.4 metres externally, and stands three storeys tall.

On the south elevation, the ground floor features a loop that has been re-cut into a Gothic quatrefoil shape, with a blocked square-headed two-light window above it, where the mullion is missing. This is situated under a panel displaying the arms of Alnwick Abbey and the Percy family, along with a loop on the second floor. The left side of the tower shows a moulded two-centred-arched doorway and a loop on the first floor, while the right side has loops on the lower floors, accompanied by a similar heraldic panel and a trefoil-headed niche above. The rear of the tower also includes loops on the first and second floors.

Inside, there is a fireplace on the first floor with a corbelled lintel, as well as sockets for the first-floor beams and corbels for the second floor. The Percy arms feature a pair of fetterlocks (handcuffs) within the usual crescent, a design associated with the 4th Earl of Northumberland, who also constructed the tower house at Hulne Friary.
