The famous lakeside sites of Switzerland have long been known for their pile dwellings and their massive quantities of Late Bronze Age metalwork. On the most recent excavations, the bronzes have been mapped in situ, allowing comparison with assemblages from dryland sites and rivers, as well as providing a context for the nineteenth-century collections. The pile dwellings emerge as special places where depositions of selected bronze objects in groups or as single discards, comparable to those usually found in dryland deposits or in rivers, accumulated in the shallow water during a unique 250-year spell of ritual practice.
