Nestled within the historic star-shaped fortress of Kastellet in Copenhagen, Denmark, stands a charming and historically significant windmill. This iconic structure, a Dutch-type mill, is a prominent feature on the King's Bastion in the southwestern corner of the citadel. It is not merely a picturesque landmark but a tangible link to Copenhagen's past, representing a crucial element of the city's self-sufficiency during times of siege. The windmill, with its robust brick base and wooden upper section, offers visitors a unique glimpse into the functional architecture of a bygone era. It serves as a tranquil focal point within the otherwise active military grounds that now double as a beloved public park, attracting both locals and curious travelers to its peaceful surroundings.
The current windmill at Kastellet was constructed in 1847, replacing an earlier post mill from 1718 that succumbed to a fierce storm on January 26, 1846. The decision to rebuild and maintain a windmill within the fortress walls was rooted in strategic necessity. Fortified cities like Copenhagen required secure and independent supplies, especially flour and rolled groats, to withstand prolonged sieges. Windmills on the bastions ensured that the garrison and city inhabitants would not face starvation if external supply lines were cut.
Historically, Copenhagen's ramparts were home to numerous windmills; in 1800, there were as many as 16 dotting the city's defenses. The Kastellet windmill holds the distinction of being the last remaining working mill of this original collection. While other mills, like Lille Mølle on the Christianshavn Rampart, were repurposed into private residences, the Kastellet mill has been meticulously preserved. Its existence underscores the ingenuity and foresight of military planners who understood the vital link between food security and defense.
What sets the Kastellet windmill apart is its enduring authenticity and operational capability. Built as a 'Dutch' mill, it features an octagonal brick base topped with a wooden structure, complete with a walkabout for setting the sails. This design was considerably more efficient than its predecessor, capable of grinding two to three times more grain. Although it ceased its daily grinding duties around 1903 or 1908, the windmill remains in full working order. This is largely due to the dedicated efforts of 'Kastellets Venner & Historisk Samling' (Friends of Kastellet & Historical Collection), a group that occasionally puts the sails on and grinds flour, allowing visitors to witness this historical process firsthand. It is a living piece of history, demonstrating the mechanics and purpose of early industrial technology within a military setting.
The windmill carries fascinating stories that connect it to Danish royalty and local artistry. It is said that the Russian Empress Consort Maria Feodorovna, daughter of Christian IX of Denmark, regularly received rye flour from this very mill. This special flour was sent to the Imperial Court in Saint Petersburg, where it was used to prepare her beloved 'øllebrød,' a traditional Danish beer-bread porridge, every morning at the Anichkov Palace.
Moreover, the area around the windmill and Kastellet itself inspired the renowned Danish Golden Age painter Christen Købke. Known as 'Kastelsmaleren' (The Citadel Painter), Købke grew up within Kastellet, and his father served as the baker (then known as a Breadbaking Entrepreneur) for the earlier mill. His many paintings captured the unique atmosphere and scenes of the citadel, leaving an artistic legacy intertwined with the site's history.
Visiting the windmill at Kastellet offers a wonderfully serene and educational experience. As part of Kastellet, which is one of Northern Europe's best-preserved star fortresses, access to the windmill area is free and open to the public daily. Travelers can wander along the well-maintained ramparts, enjoying panoramic views of the city and harbor, with the windmill standing majestically in the foreground. It provides a peaceful retreat from the urban bustle, inviting quiet contemplation about the lives of soldiers and citizens in centuries past. While the primary function of the windmill has shifted from necessity to preservation, its imposing presence and the stories it embodies continue to captivate, making it an essential stop for anyone interested in Copenhagen's rich historical and cultural tapestry.
