The Motherland Calls is a statue situated on top of the Mamayev Kurgan hill, the highest point in the city of Volgograd, Russia. As the hill offers a clear view over the whole city and the River Volga, it saw heavy fighting during the Battle of Stalingrad that proved to be the turning point in the WW II and the Slavic victory over fascism. The Motherland Calls commemorates the Battle of Stalingrad, which is considered one of the greatest triumphs in the Russian military history.
The statue was designed by sculptor Yevgeny Vuchetich (1908-1974) and structural engineer Nikolai Nikitin (1907-1973). The statue is constructed from reinforced concrete, with a system of supporting cables in the interior. When it was dedicated in 1967, it was the tallest free-standing statue in the world. The height of the main body of the statue is 52m, with the tip of the titanium sword reaching a height of 85m.
