The Round Tower

Nicknamed the Round Tower, this building is attached to its neighbour, the Trinitatis Church, built to accommodate a church, a university library, and an astronomical observatory on top of the tower. Commissioned by King Christian IV in 1637, it was completed 5 years later. Standing 35 meters tall, it is home to a planetarium and, most importantly, the oldest observatory still in activity in Europe. It is quite literally proof of the country’s astronomical talent at the time! We also owe it to Tycho Brahe, a great Danish astronomer who contributed to the country’s research on the subject. If you go to the top of the tower, you’ll have a great view of the capital’s roofs. Surprisingly, you won’t be climbing up stairs. You heard me right! Instead, you’ll be walking up a ramp. Fun fact: this means that, at the time, they could reach the top on horseback!
