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 on Soviet Square (now Tverskaya Square), located in front of the Mossoviet building (now the building of the Mayor of Moscow). 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 to the Soviet Constitution, which had been demolished in 1941.
