 Modest interior decoration—the church was twice changed into Russian Orthodox Church (1875–1918 and 1940–1944).In front of the basilica there is a detached belfry from 1878 rebuilt and heightened in the interwar times.Next to the basilica there is a Basilian Monastery founded in 1640-49 by the bishop Metodiusz Terlecki and the bishop Jakub Susza—the principal of the first Chełm secondary school.
