Today, Villa del Principe is a museum-residence: its rooms hold the traces of the same family's presence through the centuries, which is why there are such magnificent furnishings, creating an evocative “theatre of memory” which offers visitors the chance to experience history through direct contact with the objects themselves.

Of particular interest among the numerous items of 17th- and 18th-century furniture are a group of gilded wood statues and wall tables attributable to Filippo Parodi, Genoa's greatest Baroque sculptor. The bases of two wonderful tables in Florentine mosaic are attributable to the sculptor's studio.

The residence’s fine furniture was set against an elegant backdrop of textile wall hangings. Some examples of this opulence still survive today: the south wall of the Sala di Perseo retains its red ciselé velvet hangings. The two door hangings in the Galleria Aurea date back to the second half of the 17th century. They have a yellow damask ground embroidered with appliqué velvet in various colours and are dominated in the centre by the Doria coat of arms.   

The 17th-century Isfahan carpet is of exceptional rarity, produced at the Royal Palace of Isfahan under the direct control of the Persian court, and of a type known as “polonaise” after an example of its kind was displayed in the Polish pavilion of the Paris Exposition of 1866.
