Mura poligonali di Amelia

Why it matters

Amelia's polygonal stone walls preserve parts of the city's pre-Roman defences. Built from large limestone blocks fitted without mortar, the circuit was expanded over multiple phases as the settlement developed from an Umbrian stronghold into Roman Ameria.

What to notice

The polygonal masonry is most clearly expressed on the southern sides of the hill. On the north, the wall follows natural cliffs above the Rio Grande. Near Porta della Valle, large irregular blocks form an early section associated with the pre-Roman acropolis. Other portions include squared travertine courses and later repairs; some ancient masonry was incorporated into medieval fortifications.

Context and history

Archaeologists date an early defensive phase to before the Roman conquest, with major polygonal construction placed between the end of the fourth and the third century BC. The circuit developed in stages. Late Roman and medieval repairs reused the ancient foundations, and later gates were opened in the wall. Sections of the ancient masonry remain incorporated into buildings and the later walls of Amelia.
