This square, Senatskaya Ploshchad, was given the name of the Decembrists because on that memorable day, December 14, 1825, this square was the scene of the first open armed uprising of the revolutionary young noblemen, afterwards known as the Decembrists, who proclaimed the abolition of serfdom and autocracy.
The architectural ensemble of the square is remarkable for the famous Bronze Horseman Monument, the Pavilion of the Admiralty, St. Isaac’s Cathedral and the buildings of the former Senate and Synod, constructed in 1829—1834 and designed by the architect C. Rossi and the sculptors S. S. Pimenov and V. I. Demut-Malinovsky.
Now the buildings are occupied by the Central Historical Archives.
