Germany's Angela Merkel is visiting the former Nazi death camp at Auschwitz for the first time in her 14 years as chancellor, as Germany grapples with a resurgence of anti-Semitism and the growth of the far-right.
Ms Merkel is only the third German chancellor ever to visit the site in Poland, with her highly symbolic trip coming ahead of the 75th anniversary of its liberation by Soviet troops on 27 January 1945.
On the eve of her trip, Ms Merkel said that "the fight against anti-Semitism and against all forms of hate" was a priority for her government.
The 65-year-old also promised "determination" from the government in making Jewish life flourish in Germany.
Ms Merkel began the visit by walking through a gate bearing the chilling Nazi message "Arbeit macht frei" (Work will set you free).
She will hold a minute's silence by the Death Wall where thousands of prisoners were shot dead later this morning.
Ms Merkel will also give a speech during the visit, as well as laying a wreath at the nearby Birkenau camp.
The visit "is a particularly important signal of attention and solidarity at a time when Auschwitz survivors are victims of anti-Semitic insults and hate-filled emails," said Christoph Heubner, deputy chairman of the Auschwitz International Committee.
Ahead of her trip, Germany's federal states approved a €60 million donation for the Auschwitz-Birkenau Foundation.
Ms Merkel will be accompanied by Polish Prime Minister Mateusz Morawiecki and a survivor of the camp.
Josef Schuster, head of the Central Council of Jews in Germany, and Ronald Lauder, head of the World Jewish Congress, will also be taking part in the visit.
A million Jews were killed at Auschwitz-Birkenau, along with 100,000 non-Jewish Poles, Soviet prisoners of war, Roma and anti-Nazi fighters.
Many were killed the same day they arrived at the camp.
"There is no other place of memory that demonstrates with such precision what happened during the Shoah," Mr Schuster told AFP ahead of the visit.

Ms Merkel has called the Holocaust a "break with civilisation" and has voiced concern about the rise of anti-Semitism in Germany.
Her visit comes two months after an attack aimed at a synagogue in the eastern city of Halle in which two people were killed.
Police figures show that anti-Semitic offences rose by almost 10% in Germany last year from the previous year to 1,646 - the highest level in a decade.
Violent attacks went up more than 60%.
Ms Merkel follows in the footsteps of previous German chancellors Helmut Schmidt, who came in 1977, and Helmut Kohl, who visited in 1989 and 1995.
She has already visited several of the former camps in Germany over many years and has been to Jerusalem's Yad Vashem Holocaust memorial centre five times.
In 2008, she became the first German leader to address the Israeli parliament. In that speech, she spoke of the "shame" that Germans still feel.
