Jarmers Tower

Jarmers Tower is a circular red brick ruin in central Copenhagen where two major boulevards meet. The walls display a distinctive pattern made from dark-fired bricks that create a striking textured surface across the remaining structure.

This tower was built around the 1500s as part of a defensive network with multiple towers protecting the medieval city. After centuries of decline, archaeological digs between 1880 and 1885 uncovered and secured the ruins for preservation.

The tower received its name from Prince Jaromar II of Rügen, who led Wendish forces through Copenhagen's wooden defenses in 1259.

The ruins stay accessible year-round at this busy urban intersection in the heart of Copenhagen. You can visit freely whenever you pass through the area, making it easy to stop by while exploring the city center.

Archaeological excavations between 1880 and 1885 uncovered the tower's remains, leading to its preservation as the last standing medieval fortification tower.
