The Grand Mosque opened on September 23 in the Russian capital after a decade of construction work. The opening ceremony was attended by Russian President Vladimir Putin, Turkish President Recep Tayyip Erdogan, Palestinian leader Mahmoud Abbas and Kazakhstan’s President Nursultan Nazarbayev. The mosque was demolished and rebuilt to be one of the biggest mosques in the country with a room for 10,000 believers. As a result of the reconstruction, costing some $170 million, the building’s floor space has been increased twenty-fold to 19,000 square meters. Grand Mosque’s opening in Moscow - in this photo gallery by TASS.
