Nine Views (Croatian: Devet pogleda) is an ambiental installation in Zagreb, Croatia which, together with the sculpture Prizemljeno Sunce (The Grounded Sun), comprises a scale model of the Solar System.
Prizemljeno Sunce by Ivan Kožarić was first displayed in 1971 by the building of the Croatian National Theatre, and since then changed location a few times.
In 2004, artist Davor Preis [hr] had a two-week exhibition in the Josip Račić Exhibition Hall in Margaretska Street in Zagreb, and afterwards, he placed 9 models of the planets of the Solar System around Zagreb, to complete a model of the entire solar system.
On a few occasions, individuals or small groups of people, particularly physics students, "discovered" that there was a model of the Solar System in Zagreb.
[1] One of the earliest efforts to find all of the planets was started in November 2004 on the web forum of the student section of the Croatian Physics Society.
