Parco Sempione is Milan’s best-known city park, a sweep of lawns, tree-lined paths and ponds stretching between Castello Sforzesco and the Arco della Pace. Its English-style landscape offers a softer, less formal counterpoint to the grand monuments at either end.
Designed by Emilio Alemagna in the late 19th century, the park transformed former military grounds into a public green space as Milan reshaped itself after Italian unification. Today, joggers, picnickers and visitors share its winding paths, while the Triennale Milano and Torre Branca add art, design and views to the mix.
Walk through the park from the castle toward the Arco della Pace for a route that takes in both landmarks. Entry to the park is free, though attractions such as Torre Branca have separate admission; check opening hours before visiting, as they can vary by season. Cadorna and Cairoli metro stations are convenient starting points, and a picnic is an easy way to linger on a sunny day.
