In 1912 there was a parochial school in the church, where 9 boys and 15 girls studied, and a number of parish almshouse for the elderly for 5 people. Both of these buildings are now standing at the entrance of the church's fence by P. Alekseyeva Street.
Five large bulbous domes, which are placed on a massive cube of solid red bricks, make up the architectural composition of the church. The style is typical of many churches located in the central part of Russia, and, being adjacent directly to the church, the low brick tent bell tower with multiple corbel arches and other decorations supplements the general ensemble. Window architraves (each window is framed by two pilasters with capitals and completed with a helmet-shaped arch), corbel arches, balusters, arcaded frieze (made of white limestone or painted white) on the brick-red background of the church form white-stone lace, emphasizing rigor and firmness of architectural forms, solidity and, at the same time, lightness and grace of the whole structure.
The church has tree side chapels: the central one is in the name of the Twelve Apostles, the right one is devoted to Saint Nikolaos the Wonderworker, and the left one — Catherine of Alexandria. The wooden iconostasis (it is three-leveled in the central part and two-leveled in the side chapels) is gold plated and richly decorated with carvings. The six large and three medium carved icon-cases in the style of iconostasis in central nave make up a single ensemble and give an unusually joyful and elegant image of the church interiors. This impression is amplified by the fact that floors of the church, altar, solea and broad aisle in the middle of the church from the entrance doors to the pulpit are all laid out with mettlach tiles in a perfectly matched color scheme. At the western gate of the church, choir loft is constructed on cast-iron columns, where the right chorus singers are situated. The church walls are painted with artistic images and floral ornament. Copies of many famous artists' paintings decorate the church: V. M. Vasnetsov (Crucifixion, St. Great Prince Vladimir and St. Olga Equal-to-the-Apostles), prof. Markov (the Lord of Hosts), prof. Sorokin (four evangelists in the sails of the church), Hofmann (12-year-old Jesus among the teachers, the salvation of the drowning apostle Peter, the preaching of Christ from the boat), Plockhorst (Christ at Martha and Mary, the entrance of Christ to Jerusalem, Christ blesses children) and others.
The church's hallowed shrines include: Icon of the Passionate Savior,Icon of the Mother of God of Tikhvin, Icon of the Assumption (located above the royal gates of the main altar descending on the reading of the akathists at the Assumption fast), Icon of St. Nicholas which were transferred from the Tula Uspensky women's monastery; Icon of the Mother of God «Of the Three Hands» — from the Church of the Great Martyr George "na Rzhavtse"; Bogolubovo Icon of the Mother of God — from the Church of Florus and Laurus; the wooden cross which was received from Jerusalem.
