The Peter and Paul Fortress (Russian: Петропавловская крепость, romanized: Petropavlovskaya krepost') is the original citadel of Saint Petersburg, Russia, founded by Peter the Great in 1703 and built to Domenico Trezzini's designs from 1706 to 1740 as a star fortress. Between the first half of the 1700s and early 1920s it served as a prison for political criminals. It has been a museum since 1924.
