Built around the middle of the 15th century by the Roncadelli family, it then passed to the Pallavicino family and subsequently to the Marquis Ariguzzi. A skilful restoration carried out in the early 2000s harmonised the three souls of the architectural complex: the two late medieval wings, the 17th-18th century body and the part remodelled in the 19th century.
The harmonious late Gothic courtyard is surrounded on two sides by a portico with pointed arches and a wooden coffered ceiling. The rooms on the ground floor feature vaults decorated with Rococo-style stuccoes. 
Today it is home to the prestigious International School of Violin Making and the Music High School.
