Fort Alexander I
Location: Kronstadt, Saint Petersburg, Russia
"Fort Alexander 1 is a naval fortress on an artificial island located in the Gulf of Finland, near St. Petersburg and Kronstadt. From 1899 to 1917, the fort housed a research laboratory on plague and other bacterial diseases. By 1983, the fort was stripped of its fixtures and abandoned. In the late 1990s and early 2000s, Fort Alexander was a popular location for rave parties."
