Having ascended the throne, Peter I abolished the partiarchate and during the Petersburg era of Russian history, the Orthodox Church practically became a state organ. One of the signs of the Church’s subordination to the state was the consecration of churches in the name of “calender saints” who shared the names of Emperors, or in honour of saints, whose days coincided with the dates of events that were significant to the state, such as military victory. The defeat of the Turks at Chesma Bay in 1770 was marked by the founding of the Church of the Nativity of St John the Baptist, better known as the Chesma Church. The Convent of St John of Kronstadt on the Karpovka River serves as a reminder of the saint who established this very institution. At the beginning of 1917 there were over 700 churches and chapels in Petersburg. Now there are approximately 100. A number of these religious buildings have now been handed back to the Church and, thanks to the efforts of restorers, their interiors have been recreated.
