Saint Michael's Castle

St. Michael's Castle (Russian: Миха́йловский за́мок, Mikhailovsky zamok), also called the Mikhailovsky Castle or the Engineers' Castle (Russian: Инженерный замок, Inzhenerny zamok), is a former royal residence in the historic centre of Saint Petersburg, Russia. St. Michael's Castle was built as a residence for Emperor Paul I by architects Vincenzo Brenna and Vasili Bazhenov in 1797-1801. The castle looks different from each side, as the architects used motifs of various architectural styles such as French Classicism, Italian Renaissance and Gothic.
