Within the museum grounds, the Church of St Nicholas in Tolmachi is the church where Pavel Tretyakov regularly attended services. It was transferred to the museum grounds and restored in 1997, and now functions as exhibit hall and working church. The exquisite five-tiered iconostasis dates back to the 17th century. The centrepiece is the revered 12th-century Vladimir Icon of the Mother of God, protector of all of Russia.
