Alatri Acropolis

The Acropolis of Alatri, known as the Civita, is one of the most impressive pre-Roman monuments in all of Italy, crowning the hilltop town of Alatri in the Ciociaria hills of the Frosinone province in southern Lazio. It was built around the 6th century BC by the Hernici, an ancient Italic people, as the fortified citadel of their city, and what survives is its astonishing circuit of megalithic walls. These are constructed in the so-called cyclopean or polygonal technique, from enormous irregular blocks of limestone, some weighing many tonnes, fitted together without mortar so precisely that a blade cannot pass between them, a feat of engineering whose scale led later peoples to credit it to giants. The walls rise to around 17 metres in places and run for hundreds of metres around the flat summit, pierced by two monumental gateways, the larger Porta Maggiore with its single colossal lintel block, and the smaller Porta Minore. Climbing through the old town to the acropolis and walking beneath these vast ancient stones, then up onto the grassy plateau on top where a cathedral now stands, is a genuinely awe-inspiring experience, with sweeping views over the surrounding valleys. The site is open and free to visit at any time, with no ticket, and a stop here takes around an hour, longer combined with a wander through Alatri's medieval centre below, which has its own churches and lanes. The enormous walls are best seen and photographed in the raking light of early morning or late afternoon, when the joints between the giant blocks stand out. Alatri is reached by car or by bus from Frosinone, the nearest railway hub. Far off the usual tourist route, this scope-specific marvel of ancient Lazio rewards travellers fascinated by deep history and monumental stone.
