Saint Petersburg is also known as the Venice of the North and there's no mystery why. With its many beautiful buildings built along its numerous canals, it surely is a picturesque and majestic city. There are also more than 400 bridges crossing its canals thanks mainly to an urban project begun in 1703 under Peter the Great. A walking tour is a great way to see the city's monuments. Start at Petrogradskaya (metro Gorkovskaya) and go across the Troitsky Bridge from where you'll get a great view of the central part of the city including the Spit of Vasilyevsky Island, Admiralty Tower, St. Isaac's Cathedral and the Peter and Paul Fortress. Cross a bridge and you'll find yourself in one of the most charming neighborhoods you could imagine full of museums, monuments, and architectural masterpieces.
