This is a castle that is very German because it is very sober and somber. It is accessible by a path, I recommend it, because the setting is beautiful and you can take good pictures. The castle also has historical significance, both for Germany and Europe as a whole, because that's where Luther translated the New Testament into German while he was banished from the Empire. The castle is still a place of pilgrimage for the Protestants of Germany. It is a very interesting place to visit and enjoy the history.
To enter the Buchenwald concentration camp, you have to go through dense forests that were planted by the Nazis to hide the horrific place where the deported were taken. You never really feel comfortable with the idea of visiting a place where others came to die. You finally get to the camp, which gives you chills. Next to the park, there was a small zoo to entertain the children of Nazi officials. There is a door with the motto "Arbeit macht frei", of which I felt almost ashamed to take photos. In the buildings, there were jars full of teeth and hair, so people understand the atrocity of genocide. On the walls, there are huge piles of photographs of emaciated corpses. I think that a visit to a concentration camp is a great way to educate young people about the Holocaust.
