The Church of St. Nicholas in Tolmachi is both a Russian Orthodox house church and museum that is part of the State Tretyakov Gallery located in Moscow. The church is home to several religious relics and icons, including the culturally important Our Lady of Vladimir.
First mentioned in 1625 when it was a wooden church, it has since been reconstructed and restored several times. The church was ultimately closed in 1929 and became a neglected art storage house. Liturgical services were resumed after a unique arrangement between the Patriarchate and gallery were agreed to in 1993.
