Saint Michael's Castle

Saint Michael's Castle, also called the Mikhailovsky Castle or the Engineers' Castle, is a former royal residence in the historic centre of Saint Petersburg, Russia. Saint Michael's Castle was built as a residence for Emperor Paul I of Russia by architects Vincenzo Brenna and Vasily Bazhenov in 1797–1801. It was named for St Michael the Archangel, patron saint of the royal family. The castle looks different from each side, as the architects used motifs of various architectural styles such as French Classicism, Italian Renaissance and Gothic.

Saint Michael's Castle was built to the south of the Summer Garden and replaced the small wooden palace of Empress Elizabeth Petrovna. Afraid of intrigues and assassination plots, Emperor Paul I disliked the Winter Palace where he never felt safe.
