The Visconti Castle of Trezzo was a mediaeval castle built between 1370 and 1377 by Bernabò Visconti, Lord of Milan, at Trezzo sull'Adda, Lombardy, Northern Italy. It included a massive tower, 42-meter high, and a fortified bridge on the Adda river on a single arch with a record 72-meter span.
The bridge was deliberately destroyed in the 15th century during an attack on the castle. In the course of the 18th and 19th centuries, the walls of the castle were partly demolished to obtain construction materials. The stone elements of the collapsed bridge were moved to Milan for the construction of the Napoleonic Arena.
The first initiatives to preserve the remains of the castle were taken in the second half of the 19th century. The surviving parts are today reduced to the tower, the bridge abutments, some walls, and the casemates.
