Gallerie d'Italia is a museum located in Piazza Scala, in the heart of Milan. They also have various location across other cities like Turin and Naples.
At Gallerie d'Italia you can find the permanent exhibition, as well as temporary art exhibition, like the one I visited about Moroni.
It's one of my favourite museums in the city, and I love to go back to see the new exhibitions.
Adult ticket is €10, but the museum is free on the first Sunday of the month.
