Unveiled in 1748, the construction of the convent was ordered by Elizabeth Petrovna (future Empress Elizabeth I), daughter of Peter the Great.
Among the white and blue buildings, the beautiful baroque cathedral is the most famous. Bartolomeo Rastrelli (1700-1771) was put in charge of the construction that started in 1748. The Italian architect designed many palaces in Saint Petersburg, including the Winter Palace. The death of the Empress in 1762 put an end to the construction. Later, the initial projects of the Italian baroque architect were modified. The interior of the building was only completed in 1835 in a Neo-classical style.
The convent only served its purpose until 1764. Later it hosted an institute for young noble girls at the time of Catherine II. Nowadays, it is the home of various institutions. The cathedral is frequently used as a concert hall.
