Out in the Øresund, a granite giant slumbers. Middelgrunds Fort, once a sentinel of war, now whispers tales of transformation. Middelgrunds Fort stands as the world’s largest man-made island without abutment. Imagine, 70,000 square meters of rock and concrete, rising from a seabed seven meters below. King Christian IX envisioned this fortress, and between 1890 and 1894, using material excavated from Frihavnen, it became a reality. Middelgrunds Fort joined Trekroner Fort and Flakfortet, creating a formidable trio guarding Copenhagen’s harbor. Middelgrunds Fort bristled with weaponry. Five 30.5 cm howitzers, twelve 17 cm howitzers, and a host of quick-firing cannons stood ready to defend the city. During World War I, over 700 men manned this fortress, a testament to its strategic importance. The fort continued its military service through World War II and into the Cold War. It even housed a HAWK missile battery in the 1950s. Its active duty ended in 1984. Then, in 2002, a new chapter began. A private investor purchased Middelgrunds Fort. The fort briefly transformed into a hotel, its long corridors connecting almost 200 rooms. But its story doesn’t end there. In 2015, two scout organizations, with funding from A. P. Mu00f8ller and Nordea, bought Middelgrunds Fort. They renamed it Ungdomsøen, “The Youth Island”. Today, Middelgrunds Fort, now Ungdomsøen, offers a different kind of adventure. It stands as a testament to ingenuity and adaptation. From a war machine to a haven for youth, Middelgrunds Fort’s tale continues to unfold, a powerful reminder of the ever-changing tides of history.
