Leonardo was one of the favourites of the Milan court, whose life was centred in the impressive Castello Sforzesco (Sforza Castle”). Leonardo organized in the castle a famous celebration with spectacular fireworks and theatrical inventions. The Castle is now the location of many art museums, and is definitely worth a visit (you can find there, among the others, the beautiful Pietà Rondanini of Michelangelo). One of the halls of the castle, the Sala delle Asse, was decorated by Leonardo with a gorgeous naturalistic ceiling that you can admire today when visiting the Castle.

The Castle is tied to Leonardo also by the Codex Trivultianus, which is conserved there (visible only to researchers), and by the presence of the Ente Raccolte Vinciane, a cultural Institute specialized in studies on Leonardo.
