Ribera is a comune in the Province of Agrigento, Region of Sicily, southern Italy, between the Verdura and Magazzolo valleys in the so-called Plain of San Nicola. The town is connected by the SS115 state road, leading from Trapani to Syracuse. The Platani River, the third Sicilian river, flows nearby. It has enormously contributed to developing both farming and tourism in the area. Its mouth has been designated as a natural reserve.
The Chiesa Madre, founded in the eighteenth century, facing the Piazza Duomo ("Cathedral Square"). The Town Hall (nineteenth century) is in the same square. In Via Crispi is the house where Francesco Crispi, leader of the Italian government between 1887 and 1896, was born. The Garibaldi Garden offers a botanical itinerary.
Just outside the town, on a gorge overlooking the Verdura river is the Castello di Poggio Diana, built by Guglielmo Peralta in the fourteenth century. A Bronze Age necropolis (thirteenth century BC) was discovered near the town. It includes some thirty tombs in two types, "chamber"- or "grotto"-like; some are preceded by a corridor (up to 4 m long).
Also outside the town is the Borgo Bonsignore, a village founded under Fascism as part of the "colonization" policy that encouraged the creation of new villages; it has now grown as a summer resort.
