A Travel Guide to The Round Tower (2026)
Nestled in the heart of Copenhagen’s historic center, The Round Tower (Rundetårn) stands as one of the city’s most iconic landmarks. Built in 1642 by King Christian IV as an astronomical observatory, this 36-meter-tall brick tower is famous for its unique spiral ramp—designed so horse-drawn carriages could access the top—and its breathtaking panoramic views of the Danish capital. It’s not just a historical gem but a symbol of Copenhagen’s blend of Renaissance architecture and scientific heritage. Whether you’re a history buff, a photographer, or simply seeking Instagram-worthy vistas, The Round Tower offers a quick, rewarding escape with a touch of whimsy. Allow 30-60 minutes for your visit, and prepare to climb (or rather, wind) your way to the stars.
Why Visit The Round Tower?
The tower’s charm lies in its accessibility and surprise elements: no steep stairs for the main ascent (just a gentle 200-meter cobbled ramp spiraling seven and a half times around a hollow core), a glass-floored peek into the abyss below, and a rooftop platform revealing copper-green spires, colorful rooftops, and the Øresund Strait on clear days. It’s home to Europe’s oldest functioning observatory, where you might catch stargazing sessions. Plus, the ground-floor Library Hall hosts rotating exhibitions on art, science, and culture, adding intellectual depth to the experience.

By Metro: From Kongens Nytorv Station (M1/M2), it’s an 11-minute stroll west.
By Bus: Lines 1A, 2A, or 350S stop nearby at Nørreport or City Hall.

Best Time to Visit
Copenhagen shines year-round, but for The Round Tower:
Optimal Season: Late spring through early fall (May to October) for mild weather, long daylight, and vibrant city views—ideal for rooftop photos without winter chill.
Daily Timing: Arrive early (10 AM opening) or late afternoon (after 4 PM) to beat crowds, especially on weekends. Sunset visits in summer offer golden-hour magic.
Special Evenings: Tuesdays and Wednesdays (October–March, 6-9 PM) for astronomer-led observatory sessions, weather permitting.
Avoid peak midday in summer or holiday closures (e.g., December 24-25, January 1).
What to Do
Ascend the Spiral Ramp: Wind up the historic cobbled path, pausing at viewpoints and the glass floor for a vertigo-inducing look down.
Explore the Library Hall: Admire the 17th-century oak bookshelves (once housing 10,000 volumes) and current exhibitions—free audio guides available online.
Rooftop Panorama: Climb final narrow stairs to the open-air platform for 360° views of landmarks like Rosenborg Castle and the Round Tower’s own golden spire.
Observatory Peek: If open, join a free session to gaze through the historic telescope (Europe’s oldest working one).
Events: Catch concerts or talks in the Library Hall—book via the official shop.
No formal guided tours, but self-guided audio stories enhance the experience.
