Old Ruins to explore in Bremen
Bremen is Germany's smallest state. Two distinct enclaves form the state of Bremen. One is Bremen the state capital, and the other is Bremerhaven the city. Bremen is known for its rich cultural life with many theatres, libraries, archives, museums, and galleries.
Valentin submarine pens are the second-largest above-ground bunker in Europe and the most visible legacy of three major Nazi armament projects that have transformed a predominantly agricultural region since the mid-1930s. The factory was under construction from 1943 to March 1945 using forced labor, but was damaged by air-raids and unfinished by the end of the war. The Valentin factory was the largest fortified U-boat facility in Germany and was second only to those built at Brest in France.
