Peter and Paul Cathedral
Built on Zayachy Island, between 1712 and 1733, the cathedral's bell tower is the world's tallest Orthodox bell tower. It also acts as a lightning rod protecting the cathedral.
The cathedral houses the remains of most of the Russian emperors and empresses from Peter the Great to Nicholas II; including Catherine the Great, Empress of Russia for 34 years.
The Historic Centre of Saint Petersburg and Related Groups of Monuments was declared a World Heritage Site by UNESCO in 1991.
