Sviyazhsk (; ) is a rural locality (a selo) in the Republic of Tatarstan, Russia, located at the confluence of the Volga and Sviyaga Rivers. It is often referred to as an island since the 1955 construction of the Kuybyshev Reservoir downstream at Tolyatti, but it is in fact connected to the mainland by a causeway. Read more on Wikipedia
