Polnoon Castle, Medieval castle in Eaglesham, Scotland.
The remains of Polnoon Castle stand on a tree-covered mound with steep slopes leading to the Polnoon Water, containing sections of random-rubble masonry.
Sir John Montgomery built this castle in the late fourteenth century using ransom money obtained from Henry Percy following the Battle of Otterburn in 1388.
The original Montgomery armorial panel from the castle entrance now decorates the doorway of the Cross Keys inn in Eaglesham, preserving local heritage.
The castle site spans 80 meters northeast-southwest and 50 meters northwest-southeast, with most structures buried underground and covered by vegetation.
Large sections of the northeastern corner reveal evidence of vaulting, suggesting the castle was a small yet robust medieval defensive structure.
