Velleia, archaeological site in Lugagnano Val d'Arda, Emilia-Romagna, Italy

Veleia is a Roman city in the Emilia-Romagna region with ruins spread across several terraces on a hillside. The remains include a large forum with a paved square, a basilica with stone benches, public baths containing hot and cold water rooms, residential houses, and temple foundations visible across the sloped landscape.

Veleia was a Ligurian settlement of the Eleiates that became a Latin colony in 89 BCE and a municipium in 49 BCE, capital of a mountain district between the Taro and Trebbia rivers. Its growth came not from trade routes but from thermal springs used for their curative and dietary properties. It declined from the 3rd century CE and disappeared by the 5th, when landslides and the fall of the Roman Empire ended the site.

The sources call the inhabitants Veleiates, a Ligurian people, not a Celtic tribe. The town's growth owed less to trade routes than to thermal springs used for their curative properties and for food. Visitors can still see the twelve marble statues of the Julio-Claudian family found in the single-aisled basilica, now in Parma's museum.

The site lies on a hillside at 460 m, with excavated areas on terraces connected by paths and steps. The antiquarium, set up in the former excavation director's building, displays finds; most objects are in the National Archaeological Museum of Parma. Excavations resumed in 2007–2008 on the eastern domus area.

The Tabula alimentaria, found by ploughmen in 1747, is the largest inscribed bronze tablet of antiquity, measuring 1.3 by 2.8 metres. It records Trajan's mortgage scheme supporting 266 boys and 6 girls across estates in Veleia, Libarna, Placentia, Parma and Luca. Fragments were nearly sold to foundries before Count Giovanni Roncovieri and Canon Antonio Costa rescued them; the tablet is now in Parma's National Archaeological Museum.
