Anagni (aˈnaɲɲi) is an ancient town and comune in the province of Frosinone, Latium, central Italy, in the hills east-southeast of Rome. It is a historical and artistic center of the Latin Valley.
Anagni still maintains the appearance of a small medieval hill town (424 meters above sea level), with small twisting streets and steep lanes. It is built inside Roman boundary walls.
The built-up area initially included only the acropolis (the north-east zone comprising the Cathedral, Tufoli gate, and Piazza Dante) and partially defended by walls in opus quasi-quadratum (almost squared work).

Most of the boundary walls have been subjected to rebuilding and restora
