Graben is one of the most famous streets of the Austrian capital. From the XVII century it considered to be one of the most expansive and trendy streets of Vienna. It’s hard to imagine, that once there was just a ditch. Graben today is a walking street, decorated with fountains and the old mansions. We will see the Michaelerplatz square with its underground city, the Esterhazy Palace, the Plague Column and visit the oldest in Europe coffee-shop.
