In the early 1960s, the Soviet Union was way ahead of the United States in the space race.
Indeed, plans for a monument had begun three years before Yuri Gagarin even left earth.
At its apex is a rocket.
The monument is 110 meters tall, and leans on to one side at an angle of 77.
It is cladded by a suit of titanium a metal of high tensile strength and high resistance to corrosion.
In fact, many critically structural parts of spaceships are made of alloy of this very metal.
This path is known as the Cosmonauts Alley.
