Anyone who is planning to visit Auschwitz between now and 30 September should be aware of their new rules:
"Because of the large numbers of visitors to the Auschwitz Memorial, entry to the Auschwitz I site will be exclusively on a guided, group basis from 9:00 a.m. to 3:00 p.m. during the period from August 3 to September 30, 2009.
