St. Petersburg was established by Peter the Great as part of his efforts to Westernize Russia, connecting the country to the rest of Europe in a way that remote Moscow never could be. The city today has a more cosmopolitan feel than does the capital. Like Sydney and Melbourne, there is clearly a competitive aspect to the reltionship between these two cities, both of which have served as the seat of political power in Russian history.
The photo above is the Church On Spilled Blood, the city's answer to St. Basil's Cathedral, and marks the spot where reformist Czar Alexander II was assassinated in 1881.
