Rundetaarn

About

Rundetårn, or the Round Tower, is a 17th-century architectural gem in the heart of Copenhagen, built by King Christian IV as part of the Trinitatis Complex, which also includes a church and a library. Its most distinctive feature is the 7.5-turn spiral ramp—unique in Denmark—that winds around a hollow core, allowing visitors to ascend without stairs. This design once enabled horse-drawn carriages to reach the top. At the summit, you'll find a panoramic observation deck offering 360-degree views over Copenhagen’s rooftops, including landmarks like the Marble Church, Christiansborg Palace, and Rosenborg Castle. On clear days, you can even see as far as Sweden. The tower also houses Europe’s oldest functioning public observatory, open from mid-October to mid-March, where amateur astronomers and visitors can explore the night sky. Inside, the Library Hall hosts rotating exhibitions and cultural events, ranging from art and history to science. Hans Christian Andersen, the famed Danish author, frequented the tower and referenced it in several of his works. Rundetårn seamlessly blends history, science, and culture, making it a must-visit landmark that offers both educational insights and breathtaking city views.
