Church of Saints Simeon and Anna
The first stone of this church was laid in 1731 on Anna I’s request. It is dedicated to Anna the prophetess, patron saint of the Empress. The Church was consecrated in 1734 in front of Anna I.
It used to be the church of the Imperial court until 1802, and was extended and restored in the second half of the 19th century.
The church was closed after the Bolshevik Revolution and served several purposes. It hosted the museum of meteorology from 1980 to 1991 when religious services resumed.
