Seraphim Chichagov was a high-ranking Russian Orthodox prelate and former artillery officer who lived from 1856 to 1937. Born into a noble military family in Saint Petersburg, he served with distinction in the Russo-Turkish War before transitioning to religious life following the influence of John of Kronstadt. He rose through the ecclesiastical ranks to become the Metropolitan of Petrograd. His life ended during the Soviet era when he was arrested for monarchist propaganda and subsequently executed by a firing squad at the Butovo firing range.
