Holocaust Escape Tunnel

For centuries, the Lithuanian city of Vilnius was one of the most important Jewish centres in the world, until World War II, when the Nazis murdered about 95 per cent of its Jewish population and reduced its synagogues and cultural institutions to ruins. The Soviets finished the job, paving over the remnants of Vilnius's famous Great Synagogue so thoroughly that few today know it ever existed. Now, a team of archaeologists is trying to rediscover this forgotten world, excavating the remains of its Great Synagogue and searching for proof of one of Vilnius's greatest secrets: a lost escape tunnel dug by Jewish prisoners inside a horrific Nazi execution site.
