Housed inside the former Franciscan convent of Luogosanto, the museum is one of the branches of the museum system of the diocese of Tempio and Ampurias. Inside the former cells of the friars, some of which have been restored to their original state, visitors can admire the original statues and 18th-century marble bas-reliefs belonging to the country churches of Luogosanto, some paintings and sacred furnishings, and a large collection of precious jewelry donated over the centuries to Our Lady of Luogosanto as a sign of devotion. Completing the museum are a hologram of the Holy Grail, an ethnographic room, and the Center for Documentation of the Middle Ages in Gallura, which includes two interesting models of the Palace of Baldu. The museum also hosts temporary exhibitions and is a welcome and information point for pilgrims and tourists.
