Villa Rosa, an Art Nouveau building designed and built by the architect Nicolò Campora around 1905 commissioned by Monsignor Giuseppe Bertolotti, a prominent personality in Savona at the beginning of the century, today houses the Altarese Museum of Glass Art.

The variety of floral decorative motifs characterizes the rooms and fixed furnishings of the villa, which houses the collection of glass artefacts from the 17th century. to the present day, as well as tools for craftsmanship. The collection testifies to the wealth and well-being achieved by the Altare area thanks to the production and marketing of glass. The glass art, mastered by the masters of Altare and exported to Europe (Bernardo Perotto, glassmaker of the Sun King, came from Altare) and around the world (many people from Altare moved to South America in the 19th century, starting glass factories).

The Museum houses the Specialized Glass Library and a demonstration furnace for the production of blown glass is installed in the gardens of Villa Rosa.
