Unexpectedly, this is also a scenic spot. The Ring City Avenue connects several famous scenic spots in the center of Vienna. Along the Circle Avenue, you can enjoy various styles of European architecture, Gothic, ancient Greece, ancient Rome and so on. It is a visual feast. The Vienna City Hall and the National Opera House are all located on this avenue. Appreciating the trams coming and going on city roads has also become a great interest of my trip to Europe. Tracks and trams have become indispensable elements of European customs.
