The 3rd Biennale for Artistic Research in Architecture presents contemporary artistic works of architecture from across the world.

Here we offer a quick virtual tour to the tower platform, 34, 8 meters above street level.

Did a car really drive up the Round Tower’s Spiral Ramp? How often did the fairytale poet H.C. Andersen visit the tower? And why is there a bomb in the Library Hall? Get to know all the stories from the old tower with the new audio guide.

The 12-year-old choir boy August Nielsen fell down 25 metres when he was playing hide-and-seek one Sunday in 1880 and strayed into the hollow core in the middle of the tower. Today, one can safely step onto the glass floor in the open recess and look down into the depths that used to constitute Denmark’s zero point.

Join our amateur astronomers for a night of star gazing. During the winter months, the Observatory is open and manned every Tuesday and Wednesday evening from 18 to 21.
