Acropolis of Alatri

The Acropolis of Alatri is an ancient fortified site built with massive limestone blocks fitted together without mortar, featuring two gates called Porta Maggiore and Porta Minore. The structure sits on high ground and demonstrates the engineering skill of its builders, who constructed steep defensive walls using only hand tools and simple methods.

The fortification was built in the 6th century BC by the Hernici people, an ancient group living in this region who used polygonal construction techniques for their walls. A Christian sanctuary was later built on the site, reflecting how this location changed in importance and use over thousands of years.

The cathedral within the acropolis incorporates elements of a former temple, showing how pagan spaces were transformed into Christian places of worship. Walking through these rooms reveals how religious beliefs shaped the use of this ancient site over time.

The site remains open to visitors throughout the year with no entrance fees, making it accessible to explore ancient construction methods at any time. The hilltop location means you will need good physical fitness, and sturdy footwear is important for safely walking over the ancient stones.

The Porta Maggiore gate features a limestone lintel weighing about 24 tonnes, showing how ancient builders could work with enormous force and weight. This massive stone was raised into place without cranes or modern lifting equipment, highlighting the technical abilities of people living in that era.
