The Kapellbrücke in Lucerne, Switzerland

This is the Kapellbrücke or Chapel Bridge. Quoting from Wikipedia: Kapellbrücke:

The bridge is a covered wooden footbridge spanning the River Reuss diagonally in the city of Lucerne in central Switzerland. Named after the nearby St. Peter's Chapel, the bridge is unique in containing a number of interior paintings dating back to the 17th century, although many of them were destroyed along with a larger part of the centuries-old bridge in a 1993 fire. Subsequently restored, the Kapellbrücke is the oldest wooden covered bridge in Europe, as well as the world's oldest surviving truss bridge. It serves as the city's symbol and as one of Switzerland's main tourist attractions.

It is really quite long and takes some time to walk across especially if you are like me and stopping to take photos every few steps.
