Santu Lussurgiu is surrounded by oaks and chestnut forest at above sea level, at the edge of a massive extinct volcanic mountain, the
Montiferru. A rural museum features old tools for cheese production, the manufacture of iron, and related to farm work. San Pietro church, the local parish, is situated in the homonymous square, and the church of Santa Maria degli Angeli is situated near Market square. Sant'Antonio al monte (Saint Anthony of the mountain), a mountain of above sea level, is covered with various trees, including several ancient oaks. A church was built in 1944 in honor of St. Anthony, with two statues: a
Madonna, and the other of St. Anthony. There is an outdoor altar, and a path, the
Way of the Cross, with statues representing the
Passion of Christ. San Leonardo de Siete Fuentes, located at above sea level, is a small nearby settlement on the road going north from Santu Lussurgiu to
Macomer that is inhabited almost exclusively during the summer, mainly by people taking refuge at the cooler, higher altitude. It is home to a 12th-century Romanesque church, dedicated to St. Leonard. == Culture ==
