The Castello Sforzesco is the castle built by the Dukes of Milan. It is located in the heart of the city, barely 800 m north-west of the Cathedral (Duomo).
The castle is very charming in itself, particularly when you enter from the front door and try to imagine the knights and horses lining up in the square court inside.
Besides, there is an almost unknown museum in the castle (the entrance is near the northern gate) that contains many weapons from the middle ages and the Renaissance but, most of all, some rooms with frescoes on the ceilings conceived by Leonardo Da Vinci and the mysterious Pietà Rondanini by Michelangelo Buonarroti.
Michelangelo sculpted three pietà; the most famous is located in the St. Peter's church in Vatican City. The one displayed in this museum is a willingly unfinished masterpiece Michelangelo sculpted in 1563, one year before his death. No other artist has ever worked on marble at 88 years old.
In this essential, dramatic, mature work, the shapes of Jesus and Mary actually seem to come out of the raw stone. While the scene is very well composed, the attention is drawn directly on Mary, looking exhausted by the pain, feeling like she cannot hold Jesus's dead body any longer and will shortly drop it.
Jesus's dead body stands in an innatural posture underlying his death and Mary's desperation.
The entrance to the museum is free.
