One of Cagliari’s most beautiful green areas stretches across a ridge of the Buoncammino hill: a sort of ‘hanging garden’, with a long, spectacular tree-lined avenue. At the end of the avenue, you will notice the elegant Neoclassical façade of the former royal munitions depot, which has accommodated the Municipal Art Gallery since 1933. The military building was destroyed by an explosion and was rebuilt in 1828 based on a design by military engineer Carlo Boyl. After a century of use as a barracks and a warehouse and after further modernisation works, it became a museum. After crossing the garden, before entering, you can admire the façade of the building, with limestone friezes and a tympanum with three statues carved in Carrara marble above it.
