Oristano's municipal art gallery has a small but interesting collection of Sardinian paintings. Look out for various depictions of the Mamuthones, the sinister costumed characters that feature in many Sardinian carnival festivities, and Sa Sartiglia, Oristano's headline festival. For more on the festival, pop into the adjacent Sartiglia documentation centre and peruse the collection of festival memorabilia, which includes masks, costumes and an interesting selection of historic photos.
