Insider tips between daily routes and adventures

Traveling on this September day offers explorers an inspiring change from classic sights. It's not the grand museum or the palace that are the stars of the day, but rather decommissioned subway stations, former soap factories, and a ship built in 1931 in the Kiel harbor. Visitors can, for example, walk through vaults that are usually left to the echoes of time, wander through the workshops of Franconia tracing the footsteps of ancient blacksmithing, or experience railway history in a Berlin signal box with rare original equipment. The organizers emphasize that a large part of these facilities is usually not accessible, minimally signposted, and often even uncharted territory for locals.

Registration, planning, and digital assistance

On the website of the German Foundation for Monument Protection, visitors can find an overview of all participating monuments along with brief descriptions. Some tours require advance registration due to high demand and limited space. More and more organizers are offering a free app, where curious individuals can plan the route of their monument expedition and filter points of interest by region, from attics to machine halls. Those who are lucky may be able to attend spontaneously, but for some venues, the countdown to the registration deadline already starts days before September 13.

New travel experience for culture lovers

The Day of Open Monuments, an annual recurring event, is today Germany's largest cultural event. The initiator is the German Foundation for Monument Protection, which not only preserves monuments but also makes their history tangible. Local associations, owners, and private initiatives specifically invite people to their own programs, tours, and readings. For residents of Hamburg, for example, modern gas stations from the 1950s, which now house art and coffee, are an example of how the present meets the past.

Starting this summer, interested parties can find their desired monument on the official program page and receive the most important information regarding opening times, directions, and special notes. A more detailed program overview will be provided by the German Foundation for Monument Protection a few weeks before the action day on their website and in the app.
