Auschwitz is a small town in southern Poland, and the town is famous for being the largest concentration camp established by Nazi Germany during World War II. The area controlled by Auschwitz covers an area of 40 square kilometers, with three main camps and 39 small camps. The camp is free to visit, but the personal feeling must be explained by a guide to help you understand more. The camps include Auschwitz 1, Auschwitz 2 (Birkenau) and Auschwitz 3 (Monowitz), which had long been destroyed in Germany. If you don't go to the camp tour guide, you can only reach No. 2, and No. 1. The tour guide in the camp is very professional, and the explanation of the 6-hour time is very detailed and clear. It is highly recommended for a tour guide to lead the tour. Auschwitz was the site of Hitler's genocide, and as many as three million people died in the camp, which was held inmates other than Jews, as well as gypsies, Polish prisoners of war, intellectuals, members of the resistance, antisocialists, and homosexuals.
