The Arts Square Quarter, the heart of the city's artistic life, is truly enchanting with its numerous museums (Russian Museum, Russian Museum of Ethnography...), theatres and concert halls, magnificent residences of the tsars, including Peter the Great's Summer Palace and Paul I's Castle, and romantic gardens when you can enjoy a stroll in the shade of hundred-year-old trees. Round off your exploration of the area with the Church of Our Saviour of the Spilled Blood.
