It has been reported that more than 100,000 visitors attended Germany's "Open House Day for Mosques" on Friday. It is the 12th yearly open house (since 1997), and the program was organized by the Central Council of Muslims in Germany. It was also German unification day. Around 2,500 exhibitions were organized, and some reports linked the Open House Day to the controversial construction of new mosques, which are "striking at the heart of religious freedom in Germany."
