In Lazartsevo, there are two churches: the first, a single-domed, cold church with a bell tower, is dedicated to Cosmas and Damian and was built in 1799 through the efforts of the parishioners. The second church, also single-domed and warm, is consecrated in honor of Andrew the First-Called and Saints Adrian and Natalia; its construction in 1821 was made possible by the efforts of Alexandra Nikolaevna Volynskaya. Both churches have 36 desyatinas of land and serve a parish from four settlements.

According to local residents, before these churches, there was a wooden church, on the site of which the current warm church was built. However, no one remembers when exactly the first church was destroyed. The local churches have neither miraculous icons nor any ancient relics.
