The 13th-century Chiesa di Santa Maria rises above Piazza Santa Maria, the village’s focal point and the site of the Saturday market. As you wander the steep grey streets, look out for murals, including one of a notorious bandit and local lad, Giovanni Corbeddu Sali (1844–98); on a pink house near Via Cavour, another mural depicts an old lady dressed in black and bearing a rifle, symbolising Oliena's Easter S’Incontru celebrations, during which shots are traditionally fired to celebrate Christ's resurrection.
