Excerpt:
Over a thousand mosques welcomed visitors on Thursday as part of an annual event celebrating the integration of Germany's four million Muslims into society.
Organisers said they expected over a hundred thousand visitors - 80 percent of them non-Muslims - to attend events at mosques across Germany on Thursday.
The annual open day, timed to coincide with German Unity Day, was launched in 1997 to encourage people to think about Muslims' place in German society and encourage cultural exchange. This year's theme focused on environmental awareness.
