The strategic naval base of Kronshtadt was founded on Kotlin island in 1704. Kronshtadt is famous because, in 1921, its battalion mutinied against the Bolshevik’s harsh revolutionary policies. The government’s response was to slaughter almost the entire battalion. During Soviet times, the city was closed. It opened in 1996, and, today, it's a charming place to wander and look at rusting warships, naval symbols and other remains of Soviet naval glory. The city's striking Byzantine cathedral has an excellent museum of naval and local history, although it's only in Russian. There are also some very pleasant old restaurants scattered about town.
