In 2014 and 2015, new underwater archaeological sites were discovered in Lake Sāviena in the east of Latvia. The first site, according to c14 dating, goes back 4510 +/-55 years. In the other site, artefacts and ceramics from the Late Iron Age were discovered. Here, on the shore of the lake, adjacent cultural occupation of the settlement was discovered. It is possible to make preliminary conclusions that the shores of Lake Sāviena had been inhabited for a long time, which was certainly associated with the lake’s waters.
