Lavish rococo rooms provide sumptuous display space for paintings, sculptures, tapestries, and Asian ceramics. The 17th-century palace—also known as Palazzo Balbi Durazzo—was built by the Balbi family, enormously wealthy Genovese merchants. Its regal pretensions were not lost on the Savoy, who bought the palace and turned it into a royal residence in the early 19th century. The gallery of mirrors and the ballroom on the upper floor are particularly decadent. Look for works by Sir Anthony Van Dyck, who lived in Genoa for six years, beginning in 1621, and painted many portraits of the Genovese nobility. The formal gardens, which you can visit for €1, provide a welcome respite from the bustle of the city beyond the palace walls, as well as great views of the harbor.
