Coordinates: 56°49′8.1″N 45°5′34.6″E / 56.818917°N 45.092944°E Kitezh (Russian: Ки́теж) is a mythical city beneath the waters of Lake Svetloyar in the Voskresensky District of the Nizhny Novgorod Oblast in central Russia. Reference to Kitezh appears for the first time in "Kitezh Chronicle", an anonymous book from the late 18th century, believed to have originated among the Old Believers.
Legend has it that Georgy II, Grand Prince of Vladimir in the early 13th century, first built the town of Maly Kitezh (Little Kitezh) on the Volga River (today's Krasny Kholm). It is sometimes erroneously identified with Gorodets, which was actually founded some 30 years before Georgy's birth in 1189. Later on, the prince crossed the rivers of Uzola, Sanda, and Kerzhenets, and found a beautiful spot on the shores of Lake Svetloyar, where he decided to build the town of Bolshoy Kitezh (Big Kitezh). According to folk etymology, the name of the town came from the royal residence of Kideksha (near Suzdal), ransacked by the Mongols in 1237, while Max Vasmer labels the place-name as "obscure".
