Finally, the tour takes you into the scenic basement of the Bremen Theater. See all sorts of props and exciting technology here before making your way back from underground to the surface. Sunday Tour: Your journey begins at the ABC Hochbunker on Admiralstraße. Descend into the Hochbunker and discover the history of WWII air-raid shelters and the development of the bunker during the 20th century. Next, make your way to Bremen's freight yard. At the depot, you'll find the former banana ripening halls of the "fruit yard," where before WW1, inhabitants of Bremen could satisfy their cravings for exotic fruits. On your way to the next station at the Liebfrauenkirche (Church of Our Lady), cross the Bremen ramparts, where at least 8 underground bunkers are hidden. Visit an ground-level bunker at Theaterberg. At the Church of Our Lady, visit the crypt, used in the Middle Ages as a tomb. Learn more about the Übersee Museum and Bremen's only underground cobbled street. Finally, visit the old synagogue in Bremen's Schnoor neightborhood. Here you'll go down to the preserved cellar of the former synagogue, before returning above ground.

Group tours: The route for the group tour may change depending on the day and time and may include stops from both the Saturday and Sunday itinerary.
