"Nobody intends to build a wall!” These are the words uttered by Walter Ulbricht, head of state and party leader of the German Democratic Republic (GDR), at a press conference on June 15, 1961. Grenzturm Lenzen watchtower is one of the many relics that prove these words a lie. But here you will not only find a place with a dark past, but also an area that has been left to nature for decades, thus creating a fascinating symbiosis of nature and history. Climb this historic building and enjoy the view. Watch out for the wind!
