Ensemble of Public Offices with Park and Trinity Cathedral, 1796-1819

The ensemble of the Office Buildings with the park and the Trinity Cathedral in Kaluga, built in 1796–1819, became one of the largest urban planning projects of that time, and its construction cost more than 200 thousand rubles. By order of Catherine II, a new cathedral was laid to the north of the old church, inside which the Tsar's Seat with an image of Mary Magdalene was installed in memory of the liturgy of Empress Maria Feodorovna. Since 1866, the banner of the Azov Infantry Regiment, saved by Semyon Starichkov in the Battle of Austerlitz, was kept here. In Soviet years, the temple closed for worship was used as a Defense House, a cinema, a menagerie, and a sports school, but in July 1991 it was returned to the Kaluga diocese. The height of the cathedral's bell tower is about 70 meters, and in the 2000s a new multi-tiered iconostasis in the Old Russian style was installed inside.
