The invisible city of the righteous - Kitezh, Kitezh-grad, according to legend, sank under the water of Lake Svetloyar during the days of Batu's invasion. As the legend says, only the righteous and saints can see this city. Only a true believer is worthy of hearing the chime of the Kitezh bells. Until now, many Orthodox Christians go to the Nizhny Novgorod Trans-Volga region to make a pilgrimage to the shores of the holy lake. People strive for this amazing place, where the earth’s firmament has embraced a tiny diamond drop of the Universe. The lake, like an eye turned to the expanses of space and eternity, reflects in its mysterious waters reflections of the legendary past and distant future of Rus'-Russia. The book by Nizhny Novgorod writer and journalist Nikolai Morokhin invites the reader to go on a fascinating journey to Lake Svetloyar and Kitezh-grad.
