Riff Fortress

The Fort "Rif" in Kronstadt is located on the site of the St. Peter redoubt, erected in the late 18th century, and in 1909 became the third key stronghold of the Kronstadt fortress. On its territory there are three indicator pavilions with armored roofs for rangefinders and the only surviving retractable armored "hydraulic" tower. In August 1919, the fort's guns participated in repelling an attack by English torpedo boats. The object, included in the UNESCO World Heritage List, has had the status of a cultural heritage site of federal significance since 2001, and after its final abandonment by the military in 2014, it was subjected to vandalism.
