Founded by Peter the Great, construction began in 1703 and the city eventually spread over 100 islands linked by 700 bridges. It suffered severe damage during World War II, when a cruel 900-day siege claimed more than a million victims. Start with the Winter Palace complex. Formerly the residence of the czars, it is now home of the world-famous HERMITAGE MUSEUM, with celebrated works by Rembrandt, Leonardo da Vinci, and the major French impressionists. Next, drive along elegant Nevsky Prospect and admire ST. ISAAC’S CATHEDRAL with its gilded dome and marble columns. (Breakfast)
