Construction began in November 1938 using the slave labor of about five hundred male inmates from nearby Sachsenhausen concentration camp. According to SS records, it was originally planned to hold three thousand female inmates.[p. 12] Between the camp's initiation of ngày 18 tháng 5 năm 1939 and the day of liberation, an estimated 117,000 of the 132,000 women who passed through the camp had been murdered.[p. 24]
Estimates of the final death toll have ranged from about 30,000 to 90,000; the real figure probably lies somewhere in between, but so few SS document on the camp survive nobody will ever know for sure.
