On one side is the Vienna City Hall and on the other side is the Habsburg Opera House. If churches are everywhere in Prague, then in Vienna there are concert halls and opera houses everywhere. Vienna City Hall, neo-Gothic architecture, typical Central European characteristics. The city hall at night is golden. There was a long queue at the entrance of the city hall this day. It turned out that the next day was the night run day in Vienna. Everyone came here to sign up for clothing and numbers. This is also the starting point of the night run in Vienna. The next night, the running began, the roundabout tram stopped, delayed our bus trip to the sache coffee, but fortunately the sache coffee has been reserved for us.
