Short description
Even though the site has been known since 1854, no large-scale excavations have ever been conducted. The most recent investigations carried out in 2022 showed that the archaeological layers on the island and the piles in the water around the island are still  well-preserved. Based on the finds, settlement phases or at least phases of human presence are attributed to the Late Stone Age (Cortaillod and Corded Ware Cultures) to the Iron Age and the Roman period. However, the main phase of settlement is estimated to be in the Late Bronze Age (1200–800 BC).
