Visit both Auschwitz-Birkenau & Salt Mine in one day trip. Auschwitz-Birkenau is the largest death camp in human history. Currently camp is a synonym for world’s most cruel terror, genocide and atrocities. It was built by the Nazis in 1940 in Oswiecim. The total number of deaths and executions is estimated to be over 1.5-million people from 28 nationalities. Almost 90% of these people were Jews. After your visit to Auschwitz-Birkenau, head to the Wieliczka salt mine, one of the most treasured monuments in Polish cultural history. Over a million tourists from around the world visit it yearly. This unique place is listed on the UNESCO Cultural and Natural World Heritage List. The miners left dozens of sculptures and bas-reliefs cut out of the salt, keeping their work alive for many further years. There are 800 steps to climb of which 350 at the beginning take you down into the mine. There's a lift to the top of the mine at the end of the route.
