Located on the slopes of Monte Gemma (where the golden eagle nests) and clinging to the Eastern slopes of the Lepini Mountains, Supino is a long balcony overlooking the Sacco Valley.
Supino, the ancient Ecetra, is particularly known for the Sanctuary of San Cataldo, venerated every year by thousands of pilgrims. Worthy of note is the modern bronze door, depicting in bas-relief scenes of the life of the Saint and his miracles.
Along Via Roma you can admire several portals of medieval origin, with pointed or round arches, and, near the main square, the large church of Santa Maria Maggiore with elements of Baroque style.
Its five-storey bell tower with clock is interesting and particular, with its large single-lancet windows in the belfry.
Numerous sources of spring water with different properties are scattered throughout the territory. From the very popular Pisciarello Spring, especially in summer, mineral water flows, suitable for the treatment of kidney diseases.
The remains of a Roman Villa were found in the Cona del Popolo area.
The terracotta and mosaic floors, a document of the imperial age, preserve mythical marine depictions: fish, tritons, jellyfish, shells and swimming female figures.
Traditional Ciociara cuisine is at home in Supino, especially cheese, chestnuts and homemade gnocchitti longhi or strozzapreti.
