Short description
The small pile dwelling site located on the eastern shore of Lake Burgäschiwas was discovered in 1943 after the lake level had been lowered. It was excavated with the help of prisoners of war in 1944/45. While the first phase of the site at Burgäschisee-Ost was associated with the Egolzwil Culture, its main phase, dated around 3830 BC, is attributed to the classic Cortaillod Culture. There are also links to a later Corded Ware Culture phase. Furthermore, two horizons were identified which date before the pile dwelling settlements: one was associated with the Magdalenian Culture (15,000–13,500 BC) the other possibly with the end of the Mousterian Culture (around 38,000–37,000 BC).
