Sora (Italian pronunciation: ['s?:ra]) is a town and comune of Lazio, Italy, in the province of Frosinone. It is built in a plain on the banks of the Liri. This part of the valley is the seat of some important manufacturing, especially of paper mills. The area around Sora is famous for the costumes of its peasants.
Sora, an ancient Volscian town, was thrice captured by the Romans, in 345, 314, and 305 BCE, before they managed, in 303, by means of a colony 4,000 strong, to confirm its annexation. In 209, it was one of the colonies that refused further contributions to the war against Hannibal. By the lex Julia, it became a municipium, but under Augustus, it was colonized by soldiers of the legio IV Sorana, which had been mainly enrolled there. It belonged technically to Latium adiectum.
The castle of Sorella, built on the rocky height above the town, was in the Middle Ages a stronghold of some note. In 1443, King Alfonso of Naples made Sora the seat of an independent Duchy; it was afterwards seized by Pope Pius II, but being restored to the Cantelmi by Pope Sixtus IV, it ultimately passed to the duke Giovanni Della Rovere. Against Cesare Borgia, the city was heroically defended by Francesco Maria I Della Rovere. It was purchased by Pope Gregory XIII for 11,000 ducats and bestowed under the suzerainty of Gregory's son, Giacomo Boncompagni (who was the first duke of Sora of the family).
Above the town on a precipitous rock, elevation 540 metres (1,770 ft), that guards the Liri's valley and the entrance to the Abruzzi are remains of polygonal walls; here, possibly, was the citadel of the original Volscian town. Also, remains of medieval fortifications are there.
