The Cathedral of the Immaculate Conception of the Holy Virgin Mary is a neo-Gothic Roman Catholic Church in Moscow. It was built in 1911. Nowadays, the cathedral is the setting for regular liturgical celebrations in multiple languages—Russian, Polish, Korean, English, French, Spanish, Armenian and Latin—as well as benefit concerts featuring organ and church music. Its organ, the third since the cathedral's construction, was donated by the Basel Münster. The cathedral is listed as a heritage building in the Russian Federation.
