My first stop was the Prisoner of War vaults, used to hold prisoners of war in the 1700s and 1800s.

The prisoners held in these quarters came from France, America, Spain, the Netherlands, Ireland, Italy, Denmark, Poland, and Americans fighting in the War of Independence, according to the castle website.
The room was dimly lit and showed hammocks where the prisoners would sleep.
