Il Biscione a Castello Visconti in Somma Lombardo
In Somma Lombardo, very near the Malpensa Airport. If you are an "Alfisto" and fly into or out of MXP near the weekend, the castle is open for tours on weekends and holidays.

Photos are not allowed inside the castle rooms but here are a few I took in the outside areas and courtyards. There are hundreds of rooms but you only get to see dozens of them. There are amazing historical artifacts ... and dozens (or hundreds?) of additional representations of "il biscione" to be found.
