Calcata is a comune and town in the Province of Viterbo in the Italian region Latium, located 47 kilometres north of Rome by car, overlooking the valley of Treja river.
Calcata borders the following municipalities: Faleria, Magliano Romano, Mazzano Romano, Rignano Flaminio.
In the 1930s, the hill town's fortified historic center was condemned by the government for fear that the volcanic cliffs the ancient community was built upon would collapse. Local residents moved to nearby Calcata Nuova. In the 1960s, the emptied historical centre began to be repopulated by artists and hippies who squatted in its medieval stone and masonry structures.
