This Imperial legacy can still be seen clearly today in the city's famous architectural landmarks. Skyscrapers are prohibited, and the historical buildings of the central city (a World Heritage site) have been largely preserved. A hub of Russian industry, the bustling seaport fuels the city's economic revival, and travelers can take advantage of an extensive network of rail lines offering convenient domestic and international connections.
Historical attractions are the main focus of tourists visiting St. Petersburg, with highlights such as the Winter Palace and Palace Square, Peter and Paul Fortress, and the St. Petersburg Mosque. The city's status as a cultural center of Europe means a wealth of important museums, theatres and monuments for lovers of the arts, and St. Petersburg still produces some of Russia's most influential musicians and writers.
