Moscow Cathedral Mosque
The Moscow Cathedral Mosque is the main mosque of Moscow, the largest in Russia and Europe. The first building of the mosque was built in 1904, it housed a religious school which, after the revolution of 1917, became a secular Tatar school. During the Soviet period, the mosque did not close and even became the only functioning mosque in central Russia after 1936. With the 1980 Moscow Summer Olympics, the mosque, located next to the Olympic sports complex under construction, was threatened with demolition. The mosque was saved by Moscow's religious leaders and ambassadors from Arab countries. In 2011, it was demolished for the construction of a new mosque, which was opened in 2015.
