An EPFL study commissioned by the Canton of Bern has come up with three possible ways of protecting the Sutz-Lattrigen archaeological site, which offers a rare insight into the lives of pile dwellers. Sutz-Lattrigen was listed as a UNESCO World Heritage site in 2011.
EPFL experts have offered the Canton of Bern three solutions to preserve the Sutz-Lattrigen archaeological site on the shores of Lake Biel: a submerged dike, a breakwater or a protective flexible concrete mat. All three options are intended to prevent waves from eroding the objects, stilts and other remains of a civilization that dates back to the Neolithic period. The experts were commissioned by the Canton of Bern in 2015 and will present their final report to various representatives of the cantonal government on 31 October.
