The shoreline of Lake Biel has been inhabited since at least the neolithic. The remains of two neolithic settlements were found at Vingelz in 1874. The remains of the settlements became the Vingelz / Hafen archaeological site, which is now part of a UNESCO World Heritage Site. East of the Vingelz site, a late Bronze Age settlement was also discovered. After the Roman conquest, the region was part of Germania Superior. During the Roman era the Roman road from Petinesca to Pierre Pertuis or Salodurum (now Solothurn) passed through the village of Mett, which is now part of Biel/Bienne. The foundations of buildings and a 4th-century cemetery in Mett come from a late Roman or an early medieval military guard station.
