The monument to the globally-renowned developer of hydrofoils, ekranoplanes and ground-effect aircraft is in the center of Sormovo, and there is a good reason for it as it was at the Krasnoye Sormovo Shipyard that Rostislav Alexeyev became the prominent designer as he is now known. Rostislav Alexeyev pioneered the dynamic ground-effect craft, flights of high-capacity aircraft at ultra-low altitudes at high speeds, gas-turbine aircraft engines and a ski shock absorber in an aircraft. While in Nizhny Novgorod, you can take a cruise on Valday 45R, one of the ships by Alexeyev's design bureau; Valday sails to Gorodets, Pavlovo, Balakhna, Chkalovsk and Makaryev, where the Zheltovodsky Makaryev Convent of the Holy Trinity is located.
