As a result of the Holocaust, the term "concentration camp" carries many of the connotations of "extermination camp" and is sometimes used synonymously. Because of these ominous connotations, the term "concentration camp", originally itself a euphemism, has been replaced by newer terms such as internment camp, resettlement camp, detention facility, etc., regardless of the actual circumstances of the camp, which can vary a great deal.
Was there 20 years ago so was great to see how much they have developed the museum. Spent 1.5 hours ...there and had to leave to get back to coach. Well worth the visit. Would highly recommend. So informative but sad and poignant. A memorial to Anne and he family and to the atrocities of the 2nd World War. May we never visit that dark place again.! See More

Mindful that no mere visit can convey what the concentration camp was like when the Nazis ran it, I met with survivors. The week before I arrived in Krakow, I had called Jozef Stos, 89, to ask if he would discuss his years in captivity. “If I’m still alive then, sure—it’s my civic responsibility,” he said with a laugh. “But I’m pretty darn old, you know.”
Use of the word "concentration" came from the idea of confining people in one place because they belong to a group that is considered undesirable in some way. The term itself originated in 1897 when the "reconcentration camps" were set up in Cuba by General Valeriano Weyler. In the past, the U.S. government had used concentration camps against Native Americans and the British had also used them during the Second Boer War. Between 1904 and 1908, the Schutztruppe of the Imperial German Army operated concentration camps in German South-West Africa (now Namibia) as part of its genocide of the Herero and Namaqua peoples. The Shark Island Concentration Camp in Lüderitz was the largest camp and the one with the harshest conditions.
