Schleswig-Holstein Offers Over 200 Free Facilities and Historic Bridges
According to the Stiftung Denkmalschutz, more than 200 institutions participated in Schleswig-Holstein, providing free admission to landmarks such as the 113-year-old Rendsburger Hochbrücke, known as the “Eiserne Lady.” Visitors touring the bridge were advised to maintain physical fitness, as organizers specified that participants must be free of respiratory problems and cardiovascular diseases. Additional regional highlights included guided tours through the former dynamite factory of Swedish inventor Alfred Nobel in Geesthacht, climbs up the Mürwik water tower, and visits to the Prinzenhaus zu Plön, the Laman Trip House in Friedrichstadt, and the Rolf-Dietrich Schmidt Artist House in Aventoft.
In Lübeck, the city administration coordinated more than 60 events, including programs at the Burgkloster, a pilgrim hostel, and the historic fire ship “Fehmarnbelt.” Furthermore, young people involved in the Mobile Monument Preservation program of the Jugendbauhütte in Lübeck actively worked on restoring old buildings, with plans to extend their preservation efforts to the Ahrtal region.
Hamburg Celebrates a Full Weekend of Underground Vaults and Maritime Heritage
Hamburg expanded its celebration across an entire weekend, featuring programs at landmarks like the Wittenbergen Lower Lighthouse on the Rissen shore. Erected in 1899 and standing roughly 39 meters tall, the lighthouse lacks barrier-free access and does not meet modern safety standards. In the Altona district, visitors descended below Lessers Passage 4 to explore a vaulted underground ice cellar during a Sunday afternoon tour that required no advance registration.
Families and younger visitors found dedicated activities across the city, including the Speicherstadtmuseum’s “Welterbe Speicherstadt – Eine Tour für kleine Baumeister” tour held on Saturday and Sunday, alongside a candlelit treasure hunt inside the Auferstehungskirche Barmbek on Saturday evening. Additionally, the Catholic church of St. Sophien in Weidestraße welcomed guests into its monastery on Sunday afternoon.

Other regional sites open to the public included the Bockwindmühle Eldena in Greifswald, the Kurzen Trechow castle, various historic factories, and the school sailing ship Gorch Fock in Stralsund.

Meanwhile, Niedersachsen featured participation from more than 600 monuments.
