Cassano d'Adda (Milanese: Cassan su l'Adda; Bergamasque: Cassà) is a town and comune in the Metropolitan City of Milan, Lombardy, Italy, located on the right side of the Adda River.

The territory of Cassano d'Adda is divided in two parts, which are both characterised by a difference in height of 20–25 meters, by the river Adda.

The river, which still flows in a deep crack in Vaprio, stretches out in a wide riverbed in Cassano, in which its waters split into several branches separated by rocky and wooded islets.

Due to its strategic position at a crossing of the Adda river a number of historic battles took place in Cassano: Other historical people who stopped in Cassano include Napoleon Bonaparte in 1796 and 1807, and King Victor Emmanuel II and Emperor Napoleon III in 1859, just before the Battle of Solferino.

It currently houses the headquarters of the local band, of the ALS, of the ANA (the Italian association of alpine soldiers) and hosts several cultural and artistic initiatives.

Villa Brambilla It is one of the oldest palaces of Cassano d'Adda which was commissioned by don Matteo Rosales, the marquis of Castelleone, in the second half of the 17th century.

It counts 142 rooms for a total of 500 square meters and a 7-hectare park: this residence was commissioned by the d'Adda marquises in the mid-eighteenth century, probably based on a project by Francesco Croce and reworked by Giuseppe Piermarini (the designer of the Treatro alla Scala, of Milan's Palazzo Reale and of Monza's Villa Reale) in the second half of that same century.
