Located just off ul. Krakowska next to the Church of the Holy Family, this unique and original piece of public art depicts our solar system. With a large three-dimensional steel and glass orb representing the sun at its centre, the planets are arranged around it proportionally according to size and distance, with their orbits tracked in steel and the planets themselves made of massive pieces of polished marble, which rotate (just like the real planets!) with the use of unseen jets of water beneath them. Drop by after dark and you'll find it illuminated.
