Saint Petersburg Dam, Flood control dam in Saint Petersburg, Russia.
The Saint Petersburg Dam extends 25 kilometers across the Gulf of Finland, connecting Lomonosov to Kotlin Island and continuing to Cape Lisiy Nos.
Construction of this massive flood prevention structure began in 1978 and underwent multiple phases before its final completion in 2011 under President Putin's administration.
The dam represents Russian engineering capabilities, incorporating water purification systems and navigation channels while protecting the former imperial capital from destructive floods.
The structure prevents storm surges up to 5 meters high from entering the Neva Bay and includes a six-lane highway connecting both sides of the Gulf.
During its first successful operation in November 2011, the dam prevented what would have been the city's 309th recorded flood, saving 1.3 billion roubles.
