The first structure to be built in St. Petersburg, and thus the birthplace of the city, it never served its intended defensive function. Instead it has had a rich, hugely varied, and sometimes sinister history as a military base, a home of government departments, the burial ground of the Russian Imperial family, the site of groundbreaking scientific experiments, and a forbidding jail that held some of Russia’s most prominent political prisoners.
Today, the Peter and Paul Fortress is for the most part under the auspices of the St. Petersburg Museum of History, with a number of permanent and temporary exhibitions charting the various aspects of the compound’s past. While the central visitor attraction is undoubtedly the Peter and Paul Cathedral, one of St. Petersburg’s most striking buildings.
