Come to Auschwitz-Birkenau Memorial and Museum (listed by UNESCO as a Natural and Cultural Heritage site) using your own means of transport. Enjoy having tickets for a guided tour already with you and walk to the entrance. Meet your authorised, live guide on-site and follow them into Auschwitz I where you will have a chance to walk on the ground of the former camp, built in 1940 in the suburbs of Oswiecim. Use a headset provided to let you hear the guide's words no matter the distance or group size. Discover lives of people who were kept in this place while seeing exhibitions presented in barracks they used to live. The total number of deaths is estimated at over 1.5 million people, representing 28 nationalities. Nearly 90 percent of them were Jews. Once the first part of the tour is completed, take a bus available on-site and travel few minutes to Auschwitz II-Birkenau where the visit with the guide continues. Walk along the railway which facilitated transports to the other part of the camp. See ruins of gas chambers in which people "vanished" on a mass scale. You can contribute to keeping the memory of the atrocities commited there by coming there and learning more about it.
