Officials say a record number of more than 1.5 million people from around the world visited the grounds of the former Nazi German death camp of Auschwitz-Birkenau in 2014.

The Auschwitz museum said Sunday on its website most visitors came from within Poland, with large numbers of tourists also coming from Britain, the U.S., Italy and Germany. The website didn't say what the previous record was.

Between 1940 and 1945, about 1.1 million people, mainly Jews but also Poles, Roma and other nationals, were killed in gas chambers or died from forced labor, hunger and disease in the camp operated by Nazi Germans.

On Jan. 27, ceremonies attended by survivors will mark the 70th anniversary of its liberation by the Soviet army.
