The same as the other towns of the Mercure area in which Basilian monks have resided, Papasidero features many important religious buildings, such as: Sanctuary of Maria SS. of Constantinople, St. Sophia’s Chapel and St. Constantine’s Church. The ruins of the Swabian castle, the city walls and the abbey of San Pietro il Grasso are also interesting sites to visit. The "Valle del Fiume Lao" Nature Reserve stands out for its great floral and faunal diversity. The most important event of the year is in June, when Papasidero celebrates its patron, St. Anthony, and there’s the "parade of beams".
