The Immaculate Conception Church[1] (Russian: Храм Непорочного Зачатия Пресвятой Девы Марии[pronunciation?

]; Polish: Kościół wezwaniem Niepokalanego Najświętszej Maryi) is an old Catholic church in the city of Smolensk in Russia.

The construction committee included the abbot Stefan Denisevich, the author of the project — governoral architect Mikhail F. Meisher and engineer Leon Dubeykovsky.

The parish meanwhile, which meets in one place, was closed during the Great Terror of 1937 and its curate executed along with a group of parishioners.

Governor Sergei Antoufiev said in October 2010 that a new repository for files would be built and the church would be restored from 2011 through funds provided by Poland.
