ANAGNIA (mod. Anagni) ; pop. (1931), town 5,901, com mune 11,930; an ancient town of the Hernici, on a hill (1,558ft.) above the valley of Trerus and Via Labicana, Italy. Its posi tion in a fertile district soon gave it importance, and it became the seat of the assembly of the Hernican towns. In the war of 3o6 B.C. it lost its independence. It was besieged by the Saracens in 877, but in the 11th century was a place of considerable importance, the Conti and Caetani being the chief families; Pope Boniface VIII., a member of the latter, was there made prisoner in 1303. The ancient city walls, built of rectangular blocks of porous limestone, still stand, much restored in places. Within the city the only ancient remains are some massive substruction walls on the hillside. The cathedral, constructed in 1074 at the summit of the hill, is externally plain; it has a fine Gothic interior.
