Bock Casemates 
Description
Luxembourg has often been described as the Gibraltar of the North. Up until the 19th Century, when most of the fortifications were demolished as Luxembourg gained its independence, the whole city was fortified with massive walls lining the sides of the Gorge and Kilometre and kilometre of tunnels dug into the soft rock. Today most of the tunnels have been destroyed, but nearly 17Km still exist and a small proportion of these are open underneath the Bock. From the openings there are stunning views over the city and the surrounding landscape making it obvious how difficult it would be to attack the city. The tunnels don't just go along at a level they go along on multiple levels and there are lots of times when you think you may have reached the end of a tunnel only to discover a spiral staircase in a corner heading either up or down. The tour ends with you emerging onto a lower level of the bridge that the Bock stands beside.
