In Austria, it is the only country in Western Europe that recognize Islam as an official religion since 1878, and therefore, Muslims have unrestricted right to build Masjids, establish Islamic schools, and even to use collected tax money for Islamic centers!
This is a result of the relationship between the Austrian Empire and Ottoman Empire, who were allies during World War I. The number of Muslims today is 750,000+ (out of total 8.5 million) and there is no shortage of Halal here. Enjoy this photo of Masjid Telfs, with a beautiful backdrop of the Austrian Alps!
