Any palazzo or castello in Italy would be beautiful.
There is one outside of Milan named for my husband’s family.
I won’t be able to travel anymore to see it, but I hope he does.
When I was travelling in Europe many years ago now one thing I noticed was if you came across a run down house or building for some reason if it was in Italy it just looked so much better than if it was elsewhere. Not sure why but perhaps because it was sunnier and lighter than the rest of Europe.
