The oldest archaeological traces of a settlement around Murten are from the Mesolithic (8200-5500 BC). The Mesolithic finds are mostly small flint shards for use in weapons or tools. These flints were produced mostly in the swampy lowlands east of the city at Murten-Combette and Murten-Ober Prehl. While many of these flint objects are in museums, the exact discovery sites were not properly documented and have been lost or covered by later excavations. Several other sites were discovered during construction of the A1 motorway in 1976-95. These settlements are from the Neolithic (5500-2500 BC) and the Bronze Age (2300-800 BC).
