Ostankino Tower
"The Motherland Calls" is highly complex from an engineering point of view, due to its characteristic posture with a sword raised high in the right hand and the left hand extended in a calling gesture. The technology behind the hollow statue is based on a combination of prestressed concrete with wire ropes, a solution which can also be found in another work of Nikitin's, the Ostankino Tower in Moscow. The sculpture is hollow. Inside, the entire statue consists of separate cells or chambers, like rooms in a building. The concrete walls of the sculpture are thick.
