At the north-west corner of St Andrews Castle’s courtyard stands a sea tower that served as a prison throughout the castle’s active life.
The upper floors are thought to have been used to imprison nobles, as well as accommodation for guests. The ground floor contained two chambers. The first was an unlit chamber with a narrow ventilation slit in the east wall. The second contained the castle’s infamous bottle dungeon, a 7.3 metre deep chamber cut into the rock. Common prisoners were lowered into the claustrophobic dungeon, which is around 4.6 metres wide at the bottom. To this day it is believed to have been one of the grimmest of Scotland’s many castle dungeons.
