Olevano sul Tusciano takes its name from the river Tusciano that crosses it in its greatest extension and from the olive tree whose cultivation constitutes the primary economy of the population. A feudal town from the 11th to the 16th century, Olevano encompasses a historical, artistic and natural heritage that is still intact. Among the various sites is the 'Grotta di S. Michele' (St. Michael's Cave), which opens in a natural cavity on the slopes of Mount Raione, created by the millennial work of water and inside which one can admire typical Byzantine iconography. Also worth visiting is the 18th century Palazzo dei Baroni Moscati, with architectural and decorative features of the Vanvitellian school, and the Convent of S. M. di Costantinopoli dating back to the 16th century and built by the Dominicans. Dominating the entire plain as far as the sea, there is the 'Castrum Olibani' - a fortified village from the 6th-7th centuries, the main nucleus of which is located between the two rocky boulders on the summit of the mountain of the same name. The function of the fortress was mainly to house the population during attacks and pirate raids from the sea. Typical local products include olive oil, which goes very well with Salerno dishes, and exquisite mozzarella made from the milk of buffaloes bred in the Sele and Tusciano plains.
