Kastellet

Overview

Nestled in Denmark's vibrant capital, Copenhagen, lies Kastellet, an exceptionally well-preserved 17th-century fortress. This unique star-shaped citadel, known as 'The Citadel' in English, offers a captivating blend of military history, architectural beauty, and tranquil green spaces. More than just a relic of the past, Kastellet remains an active military area while simultaneously serving as a cherished public park, inviting both locals and travelers to explore its historic grounds. Its distinctive pentagonal shape, complete with five bastions and a surrounding moat, makes it a prominent landmark near Copenhagen Harbour. Walking through Kastellet provides a serene escape from the urban bustle, offering picturesque views and a palpable sense of stepping back in time.

History & Cultural Background

The origins of Kastellet trace back to 1626 when King Christian IV initiated its construction as St. Anne's Redoubt, an advanced outpost to fortify Copenhagen's defenses. Following the Swedish siege of Copenhagen between 1658 and 1660, the necessity for a stronger defensive structure became evident. The fortress was subsequently expanded and completed in 1664 under King Frederick III, with the design attributed to the skilled Dutch military engineer Henrik Rüse. This transformation resulted in the iconic star-shaped fortress, a state-of-the-art example of Renaissance military architecture featuring bastions and moats for optimal defense. Throughout its long history, Kastellet played a vital role in Danish military defenses, participating in conflicts such as the Battle of Copenhagen in 1801 and 1807, and later served as a barracks for the Danish army during the 19th century. Even in the 20th century, its strategic importance was highlighted when it was occupied by German forces during World War II. Today, Kastellet continues to house various military activities, including the Danish Defence Intelligence Service and the Home Guard.

What Makes It Special

Kastellet stands out as one of Northern Europe's best-preserved star fortresses, a testament to 17th-century military engineering. Its unique charm lies in its dual identity as an active military installation and a peaceful public space, where history coexists with everyday life. The architectural grandeur of its Dutch Baroque gates, the King's Gate and Norway Gate, dating back to 1663, immediately captivates visitors. Within its ramparts, you will discover a collection of historic buildings, each with its own story. The Citadel Church, built in 1704 in a beautiful Baroque style, and the Commander's House from 1725, with its distinctive yellow facade, are prominent examples. One of the most iconic features is the historic windmill, a Dutch-type mill rebuilt in 1847, which replaced an earlier structure from 1718. This windmill is a picturesque reminder of the fortress's self-sufficiency during sieges. The opportunity to walk along the grassy ramparts, which offer expansive views of Copenhagen Harbour and the surrounding city, provides a truly immersive experience.

Stories, Fun Facts & Local Details

Kastellet is rich with fascinating tales and details that bring its history to life. The windmill, for instance, was essential for grinding grain to supply the soldiers stationed within the fortress, ensuring food provisions during prolonged sieges. An intriguing historical detail concerns the prison cells adjacent to the Citadel Church; holes in the wall allowed prisoners to listen to church services from their confinement. This unique architectural feature offers a poignant glimpse into the lives of those held within the fortress walls. The renowned Danish painter Christen Købke, famous for his Golden Age works, drew much inspiration from Kastellet, as his father owned the mill, making the fortress a recurring motif in his art. For those visiting, it's worth noting that while the ramparts are perfect for a stroll or a jog, walking on the grass inside the ramparts is generally not permitted; visitors are encouraged to keep to the cobblestone paths. This rule helps preserve the historic grounds while maintaining its active military function. The fortress also hosts an impressive Monument for Denmark's International Effort since 1948, honoring Danish soldiers who have served internationally.
