Castello Sforzesco - Piazza Sempione di Milano

The Castello Sforzesco (Italian for "Sforza's Castle") is a medieval fortification located in Milan, Northern Italy. It was built in the 15th century by Francesco Sforza, Duke of Milan, on the remnants of a 14th-century fortification. Later renovated and enlarged, in the 16th and 17th centuries it was one of the largest citadels in Europe. Extensively rebuilt by Luca Beltrami in 1891-1905, it now houses several of the city's museums and art collections.
Parco Sempione ("Simplon Park") is a large city park in the historic center of Milan, region of Lombardy, Italy.
The vaguely polygonal park is anchored to the southeast by grounds of the Sforza Castle and a linear axis leads in the northwest to the Arch of Peace. The perpendicular axis to these two landmarks is flanked on the northeast by the oval Arena Civica and in the southwest by the Palazzo dell'Arte ("Palace of Art"), built in 1933 to house the Fifth Triennale di Milano art and design exposition, and now a permanent museum, theater, and exhibition hall. Contemporary and near the Palazzo dell'Arte is the steel tower-spire Torre Branca, designed in 1933 by Gio Ponti as Tower Littoria (Lictor's Tower). Near the Arena, stands the public aquarium.
