- Gloomy underground passages wind their way under the castle
Under Kronborg’s four protruding bastions lie the castle's underground passages. The casemates are gloomy, cold and damp, but have saved many lives during times of war. The underground passages have protected soldiers when enemy bullets were fired into Kronborg.
Soldiers were able to barricade themselves inside the casemates for weeks. They had room for horses and soldiers and there were provisions to feed 1,000 men for up to six weeks. The casemates were built in 1574-76, when the medieval fortress Krogen (literally “The Hook”) was rebuilt into the renaissance castle of Kronborg.
