She defended the lack of surveillance cameras at the site, saying that she didn’t want to turn Dachau into a “maximum-security unit.”
But she said that that decision may now have to be reconsidered.
In a statement, Yad Vashem, the Holocaust memorial in Israel, said: "The theft of such a symbolic object is an offensive attack on the memory of the Holocaust.”
Dachau was the Nazis’ first concentration camp. Set up in 1933, it saw the death of more than 30,000 people before its liberation by the United States army in April, 1945.
The crime follows a similar theft in 2009, when the ‘Arbeit Macht Frei’ sign above the gates of Auschwitz was taken. Three men were jailed for stealing the sign, which was recovered in northern Poland.
