'Harry' was the nickname of the tunnel that the Allied airmen imprisoned by the Nazis in Stalag Luft III during WWII successfully completed and famously escaped through in what became known as 'The Great Escape.' Today, as part of the Prisoner of War Camps Museum in Żagań, the entrance and exit of the tunnel are marked with commemorative stones and connected with a line of pavers which show where the 102-metre tunnel ran, plus where the staging posts, nicknamed 'Leicester Square' and 'Piccadilly Circus,' were located.
 

These pavers tracing the underground course of the tunnel (which was dug at a depth of 9 metres) carry the names of all of those who escaped, with those who were later recaptured and executed by the Nazis marked in black lettering (see photos by M. Kitson). A guard tower has been reconstructed as well as a small section of fence to give you an idea of how far the escapees dug. Signs among the trees show how life looked as the area where the camp stood has now been reclaimed by the trees.
