The Statue of Yuriy Dolgorukiy is an equestrian statue which commemorates the founding of Moscow in 1147 by Yuriy Dolgorukiy (1099 – 1157). Dolgorukiy was the Grand Prince (Velikiy Knyaz) of the Kievan Rus' (Kiev) and a member of the Rurik dynasty. On 6 June 1954, the statue was erected in Tverskaya Square (then called "Soviet Square"), located in front of the building of the Moscow Mayor (then, the "Mossovet"). The sculptors were Sergei Mikhailovich Orlov, A. P. Antropov, and Nicholay Lvovich Shtamm. The architectural design was by Viktor Semenovich Andreyev. The statue replaced the monument of the first Soviet Constitution that was broken down in 1941.
