Eburodunum, Archaeological site in Yverdon-les-Bains, Switzerland.

Eburodunum is a Gallo-Roman vicus site in Yverdon-les-Bains, largely buried under modern buildings. On a grassy slope, low ruined walls of small grey and brown stones set in mortar trace rectangular and curving foundation lines, with squared corner blocks; a long straight wall runs along the upper left and a curved section arcs across the foreground. A local association rebuilt part of the fort's north wall in stone to about 50 cm high.

Eburodunum grew from a Celtic oppidum founded around 370 BC into a Gallo-Roman vicus from the 1st century AD, with a fort likely guarding the passage and port on the Thièle. In the second half of the first millennium the site was abandoned after a change in the level of Lake Neuchâtel; the buildings were destroyed and their stones largely reused for the medieval town and castle on the new shore.

The site reveals how Roman communities organized their daily life and commerce in this region. The finds show connections between local inhabitants and the wider Roman world.

The site is accessible on foot and offers information displays on the grounds. Wear comfortable shoes and allow time to explore the entire area at a steady pace.

The site was abandoned in the second half of the first millennium when a change in the level of Lake Neuchâtel shifted the shore; the medieval town and castle were then built on the new shoreline. Its stones were largely reused, and most of the vicus now lies buried under modern buildings.
