Colombarone, Archaeological site in Pesaro, Italy

Colombarone is an archaeological area on the last stretch of the ancient Via Flaminia, at Strada San Cristoforo 136 near Gradara and Gabicce Mare. It holds a late Roman villa of the 4th century with five aligned rooms and polychrome and black-and-white mosaic floors, later turned into the church of San Cristoforo ad Aquilam.

Annibale degli Abati Olivieri dug here in the 18th century, believing he had found the basilica of San Cristoforo ad Aquilam, where Pope Zaccaria met the exarch Eutichio in 743. Excavations resumed in 1983 under Nereo Alfieri and Pier Luigi Dall'Aglio and opened to visitors in July 2008. They confirmed the basilica but showed Olivieri's finds belonged to a late Roman villa of the 4th century.

The museum displays objects from daily life in the Roman period, including lead pipes, bronze items, glass, and marble pieces. These finds tell stories about how people lived and what they used in their homes and activities.

The archaeological site has been open since 2016, with the attached Antiquarium museum featuring multimedia displays opening in 2019. Visitors should wear sturdy shoes as the terrain is uneven and there are several building sections to explore.

The 18th-century scholar Annibale degli Abati Olivieri dug here and believed he had found the basilica of San Cristoforo ad Aquilam, where Pope Zaccaria met the exarch Eutichio in 743. Excavations from 1983 showed the structures he mapped were actually a late Roman villa of the 4th century.
