"As part of the program of state atheism, the church was confiscated from the Russian Orthodox community as part of the Soviet Union's anti-theist campaigns and has operated as a division of the State Historical Museum since 1928. It was completely and forcefully secularized in 1929 and remains a federal property of the Russian Federation. The church has been part of the Moscow Kremlin and Red Square UNESCO World Heritage Site since 1990. It is often mislabeled as the Kremlin owing to its location on Red Square in immediate proximity of the Kremlin." -wiki
