Count Bartolomeo Arese commissioned the architect Richini to design this palace in 1648. Then in the 18^th century Bartolomeo Bella put on the animated Rococo façade. The portal is flanked by two Atlases upholding the balcony. On the upper part of the front is the coat of arms of Litta Visconti Arese supported by two Moors. Inside, the rooms have retained their cold 18^th century splendor; the Hall of the Mirrors, one of the most elaborate with its gilded carvings, the Red Room with its damask lined walls, and the Duchess' Living Room with refined Chinese art works.
