Gallileo Gallilei at Plaza de Oriente (Madrid)

In Madrid, next to the Royal Palace, in the middle of the Plaza de Oriente you can enjoy a wonderful statue of Felipe IV.
This equestrian statue was made by the Italian sculptor Pietro Tacca, who used a design by Diego de Velázquez. But the most amazing thing about this statue, if you look closely, is how it keeps its balance, since the Horse has its two front legs raised, it is a physics ingenuity to keep this statue; and for this the artist had the collaboration of scientist Gallieo Galliei, who assured his stability, playing with solid parts (in the back of the sculpture) and hollow in the front.
If you visit the Royal Palace of Madrid, do not miss it !!!
