The summer church is a square building with wall thickness of 130 cm and a height of 12 arshins. Its vault has a barrel shape and is decorated with a series of kokoshniks on the outside, while inside it is column-free, which distinguishes it from other churches in the city. Such column-free churches are characteristic of Moscow architecture of the 17th century, an example of which is the Epiphany Church in Yaroslavl.

The church's windows, adorned with stone carvings, are arranged in two tiers, making the interior space high and bright. The roof is almost flat, with four slopes, featuring five small domes on high drums, decorated with wooden eight-pointed crosses covered with white iron. The corner drums are blind, while the central, larger one has clerestory windows. The altar with three semicircular apses adjoins the church from the east. On the south side, there is a warm stone chapel, built in 1735 with the blessing of the Archbishop of Rostov, Joachim, in the name of St. Alexius, Metropolitan of Moscow and all Russia, replacing an old wooden one. To the west, a tented bell tower is attached, the base of which serves as a porch, as well as a watchman's room. The square of the bell tower reaches the second tier of windows, the octagon reaches the level of the lower roof slope with arched openings and a stone parapet, and the tent has one row of clerestory windows and a small dome on a narrow neck topped with a cross. The bell tower houses six bells. In the cold church, there is the altar of the Annunciation of the Blessed Virgin Mary, and in the warm chapel, that of St. Alexius.

During Soviet rule, the Annunciation Church was one of the first to be plundered. It was officially closed on November 21, 1929. By spring 1931, the building was used as a club named after Stalin. Valuables were confiscated, icons were partially transferred to the Resurrection Cathedral, partially destroyed, bells were thrown down, and parishioners were dispersed. The bell tower and chapel were destroyed and dismantled for bricks, leaving only the square church.

The club did not last long, and a bakery was opened in the church building, which operated until a fire in 1949, when barrels of oil exploded in the warehouse, causing serious damage to the church. Attempts were made to dismantle the walls for bricks, but the strength of the masonry prevented this. However, the altar part and the southern chapel were destroyed, and the bell tower was toppled by tractors. Since then and until recently, the church had a dismal appearance, but fortunately, it did not completely collapse.

In the 1970s and 80s, attempts were made to restore the Annunciation Church as a monument of architecture, but they were abandoned at the initial stage. In the mid-1990s, the church was handed over to the Diocese, and restoration work began.

In 2000, a parish was registered in the church, and a temporary altar was installed. The first Liturgy was held on the feast day of St. Alexius. Since then, Sunday and holiday services have been regularly conducted in the church.
