The Museum Casa Deriu is located in Bosa in Corso Vittorio Emanuele, in the area called “Sa Piatta”, in a 19th century building.

The building, on three floors, is the result of the unification of several dwellings and is, with its frescoed vaults and furnishings, a beautiful example of a bourgeois dwelling in the old town centre of Bosa. The exhibition is structured in three themed areas: one part hosts temporary exhibitions on Bosan customs and traditions. Another part includes the so-called piano nobile, an authentic stately flat that has remained exactly as it was in the 19th century. The centrepiece of the museum is the permanent exhibition of Melkiorre Melis‘ artistic production, which consists of various works of pictorial value and historical representation. He distinguished himself in advertising graphics during the fascist era.

There are numerous works on display, as the artist dedicated himself to the creation of furniture, objects and ceramics, and also includes the African period thanks to his Libyan experience as director of the School of Indigenous Arts and Crafts in Tripoli.
