[4] On 19 March 2010, the grand opening of the current Museo MAGA began with an exhibition dedicated to Amedeo Modigliani.

The modern makeover was completed to create a relationship with younger visitors and a more contemporary approach to the appreciation of the arts.

Two important buildings were built on the ruins of the castle of Cotta by the Archbishops of Milan: The Palazzo Leone da Perego and The Palace of Ottone Visconti.

The exhibition is dedicated to the CAM because the MAGA museum has the historic archive and the important collection that belongs to the Foundation of Angelo Bozzola of Galliate.
