Calcata borders the following municipalities: Faleria, Magliano Romano, Mazzano Romano, Rignano Flaminio.
In the 1930s, the hill towns'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. Many of the squatters eventually purchased their homes, the government reversed its condemnation order, and the residents of what had become an artistic community began restoring the ancient town.
This trend has continued. Today the town has a thriving artistic community described in The New York Times as what "may be the grooviest village in Italy, home to a wacky community of about 100 artists, bohemians, aging hippies and New Age types."
The historical centre now includes restaurants, cafes, and art galleries.
