ZÜRICH, SWITZERLAND—Swissinfo.ch reports that traces of a Bronze Age village were found under a thick layer of mud and 13 feet of water in central Switzerland’s Lake Lucerne during pipeline construction. Researchers from Zürich’s underwater archaeology department recovered five pieces of pottery and about 30 stilts that would have supported houses positioned on the lake’s edge some 3,000 years ago. The settlement suggests that the area was inhabited about 2,000 years earlier than previously thought.
