A curious one, to say the least. The Old Rhine Bridge is exactly what the name suggests — an old bridge over the Rhine — but there is plenty to like about this unorthodox wooden structure. The covered bridge is 135metres long but best enjoyed from the outside, its wooden architecture paying homage to the mountain houses found all around the region. The bridge is the border between Liechtenstein and Switzerland and houses one of the few spots where the border is actually marked.
