Polish police said on Sunday they had detained a Dutch tourist for giving the Nazi salute at the site of the former death camp, Auschwitz-Birkenau.
"Officers from [the southern city of] Oswiecim detained a 29-year-old woman from the Netherlands today," regional police tweeted.
"The tourist had been performing the Hitler salute in front of the Arbeit Macht Frei [Work Sets you Free] gate.
"The detainee was charged with engaging in Nazi propaganda. She confessed."
Prosecutors issued her with a fine as punishment, which she accepted, the Polish news agency Pap reported.
It said she was caught in the act by guards while posing for a photo taken by her husband.
"She explained it away as a bad joke," regional police spokesman Bartosz Izdebski said.
Nazi Germany built the death camp in Oswiecim after occupying Poland during the Second World War.
The Holocaust site has become a symbol of Nazi Germany's genocide of six million European Jews, one million of whom died at the camp between 1940 and 1945 along with more than 100,000 non-Jews.
