In the past Merkel said that immigrants should get used to Germany's way of life and that mosques should not be higher than churches.
Chancellor Angela Merkel said Germans had for too long failed to grasp how immigration was changing their country and would have to get used to the sight of more mosques in their cities, according to a newspaper.
Germany, home to at least 4 million Muslims, has been divided in recent weeks by a debate over integration sparked by disparaging remarks about Muslim immigrants by an outspoken member of the country's central bank.
"Our country is going to carry on changing, and integration is also a task for the society taking up the immigrants," Merkel told the Frankfurter Allgemeine Zeitung daily.
"For years we've been deceiving ourselves about this. Mosques, for example, are going to be a more prominent part of our cities than they were before," she added.
