Angela Merkel has laid a wreath at the former Nazi concentration camp of Dachau, in the first such visit to the site by a German chancellor.
She made a short, emotional speech saying the camp "fills me with deep sadness and shame" and said it was a warning of the dangers of indifference.
The visit took place during Mrs Merkel's election campaign and was followed by a rally in a beer tent.
Political opponents called the combination "tasteless".
