Visitors can watch the fort's 15 cm cannon fire a salute, the largest gun at Garderhøj Fort and currently the only one in working order. The gun is loaded with half a kilogram of loose powder, so the bang is loud: around 128 decibels under the dome and 80 decibels on the rampart around the fort. The cannon crew wear hearing protection and ear plugs for the firing.
After the salute, there is a chance to tour the fort's tower, though this costs an entrance fee.
