Pretty much every state . Do not do this , you will be arrested <| sep |> Aha , I always assumed it was based on contracts , like I ' ll pay you when I have the money kind of thing , but I ' m probably wrong on that . <| sep |> I used to live in Dresden in former East Germany , which during WWII was razed to the ground by the Allies resulting in the deaths of 20 , 000 civilians and the destruction of 34 km 2 of the city , including the entire medieval city centre . On the 13 th February every year , the anniversary of the bombing , there ' s a remembrance gathering but the date is also used by neonazis . It ' s often a very busy night for the police , not because they have to control the neonazis , but because ordinary Germans hate them so much that they need police protection when they organise public gatherings . Interesting side note In all other medieval European city centres , which are hundreds of years old , the stonework on buildings has been blackened and eroded by pollution and hundreds of years of weather . Since the centre of Dresden was completely destroyed , and then rebuilt exactly as it was but with mostly brand new stone , it ' s not eroded or blackened at all . The buildings all look exactly as they did hundreds of years ago when they were first built , it ' s beautiful . You do get a reminded of history though , the Frauenkirche for example is a beautiful sandstone colour , but some of the blocks of stone are black . Those are the ones from the original building that were in a good enough condition to be reused , after being bombed and enduring a firestorm . It ' s difficult to walk past some of those buildings without being reminded of the consequences of war .
