When reading up on tips for places to check out in Milan, Castello Sforzesco popped up as a destination with multiple museums so I added it as a stop in my itinerary. Upon reaching it in person the proportions and grandeur of the castle fortifications really blew me away! Sitting along the southeastern edge of Parco Sempione, this imposing structure dominates the entire side of the park. Approaching from Sforzesco Plaza, you can't miss the fountain in front of a massive red brick wall with main front gate tower and stout 6-story tall turrets on each wall corner.
Visiting the castle grounds is free and on a sunny afternoon in April it felt like half of Milan was here. Tourists and locals alike, checking out the views, walking dogs, taking the family for a stroll, setting up a picnic on park grounds surrounding the castle--you name it there were tons of people doing it. Even then, the inside courtyards of the castle were huge and from above people looked like little ants in a terrarium. The only place it got uncomfortably crowded was in a couple of the narrower gate corridors leading thru the center of the castle to the rest of Parco Sempione to the west, a couple spots where due to the crowds, walkways normally wide enough for 5-6 people to walk comfortably side by side felt cramped. Other than that pretty easy to navigate.
The layout of museums inside the castle are rather confusing, they could certainly do a better job of explaining how this works. It's actually a series of museums all connected inside, with the starting point entrance to the total complex at the Museo Archeologico Sezione Preistoria e Protostoria (archeological museum). This is where the main ticket counter, small lobby and downstairs locker area are located. They require jackets and any bag larger than a small purse to be held in a locker. It's free to use them--if you don't have a one Euro coin (used to trigger the lock mechanism, returned to you upon unlocking the locker), they can give you a fake "coin" at the ticket counter.
Once you enter the archaeological museum, the flow of exhibition continues in one direction and at the "end" of each smaller museum, you have the choice of exiting or continuing on to the following museum. The exhibitions get more extensive as they progress so unless you have a clear idea of what you are there to see you can basically spend a couple entire days here if you go very slowly. Archeological works, medieval art, decorative arts, instruments, ceramics, etc) In 3 hours I basically took my time in about 40% of it then rushed thru the last 60% prior to them closing. It's hard to tell how far along you are in the total floor plan since the path of where each smaller museum is in relation to the others isn't super apparent. Also the museum staff are super militant about not backtracking in the museums which made it harder bc again you have no idea how far along you are.
Bathrooms are available though you may need to ask since directions are not super apparent. Usually there were signs towards the end of each smaller museum. Also not a whole lot of places to sit down and rest within each exhibit. My feet hurt towards the end and kinda just had to deal with it. Easily accessible via public transport--nearest metro stops are Cairoli, Lanza and S. Ambrogio. A lot of buses also stop nearby.
