Castello Sforzesco
Piazza Castello, Parco Sempione, Arco della Pace
Sforza Castle closes Parco Sempione. The castle picture gallery is inside the walls, the walk across the park ends at the Arch of Peace, and Triennale Milano sits on the west edge.

Sforza Castle closes Parco Sempione: the pinacoteca is inside the castle, the park avenue leads to the Arco della Pace, and the Triennale sits on the western edge.
Morning or late afternoon, when the park has shade. At noon the castle courts are open and full.
Sleep by the park only if you want the castle at first light. The park empties in the evening. The suitcase is calmer in Brera or by the Duomo.

You can walk through the castle: the park is already visible from the courtyard, which is shorter than going around the walls. The Arco della Pace is at the far end of the avenue; the Triennale is on the western edge of the same lawn, not beyond the arch.
