The Leaning Tower of Pisa, known for its unusual leaning, was built in 1373 from white marble in the ancient city of Pisa in Italy. Its construction lasted 200 years. The world-famous scientist Galileo used the Leaning Tower of Pisa for his experiments. From its last floor, he threw various objects to prove that the falling speed does not depend on the weight of the falling body. A copy of the tower can be assembled with your own hands from the wooden parts included in the 3D model. They only need to be detached from the tablets and assembled without glue according to the instructions.
