Discover more about Sprogø

Floating midway between the islands of Zealand and Funen, Sprogø is a windswept outpost of Danish history and nature, visible to millions who cross the monumental Great Belt Bridge above. But very few have actually set foot on Sprogø, as it remains largely closed except for special guided tours. Its isolation is both geographical and historic: for centuries, Sprogø’s position in the middle of the strait made it crucial for maritime navigation, telegraphs, and later, as a site for the iconic lighthouse that still stands on the island’s crest. Yet Sprogø’s story is also entwined with Denmark’s more complex social legacy. From 1923 to 1961, the island was the site of a notorious women’s institution, dedicated to detaining women deemed 'morally deficient' by the state. The remnants of this era linger in austere buildings and haunting stories, and the island is now a point of reflection for Danish society. Recent preservation efforts focus both on Sprogø’s rich biodiversity—its meadows, seabirds, and wildflowers—and the cultural memory his preserved here. Visitors who join a rare, pre-booked guided tour are treated to windswept vistas, the wild roar of the surrounding sea, tales of shipwrecks, lighthouses, and the island’s changing roles through war and peace. Ruined bunkers and the elegant lighthouse provide atmospheric photo opportunities, while your guide may recount stories of isolation, resilience, and transformation. On stormy days, Sprogø feels even more remote—an unpolished, evocative piece of Denmark rising above the tides. Sprogø is not a typical tourist stop: it is a powerful, thought-provoking North Sea island with a unique blend of natural and human drama.
