Excavation in Concordia began in the last century. A Roman bridge was found under the town and a 4th-5th century B.C. burial ground known as the soldier’s burial ground was discovered on the left of the River Lemene.
In 1983 remains of the Baths were brought to light and, in the square in front of the cathedral, remains were discovered of homes with drains and floors, as well as a part of the Decumanus Maximus, the main street of the town.
The via dei Pozzi Romani (a side street of via S.Pietro) saw the discovery of two Roman wells.
