Origin and history

The Lons-le-Saunier tumulus is a funerary monument dating from the Chalcolithic period, a pivotal period between the end of Neolithic and the beginning of the Bronze Age. Located in the Jura department, it illustrates the funeral practices of this period, marked by the construction of terres to honor the deceased. This type of structure, typical of protohistoric societies, served as both a burial and a territorial marker for local communities.

Ranked as a Historic Monument by order of 31 May 1976, this tumulus is now protected as a national heritage. Available data indicate that it belongs to the municipality and is referenced in the Merimée database under INSEE code 39300. Although its precise location is approximate (noted 5/10 in terms of precision), it remains an important archaeological vestige to understand the cultures of the Bronze Age in Franche-Comté.

Sources also mention possible confusion about its exact address, with GPS coordinates pointing to Montmorot, a nearby municipality. This geographic uncertainty reflects the documentation challenges of older sites, often identified by approximate benchmarks. Despite this, the tumulus retains an undeniable heritage value, linked to its seniority and its role in local history.

No information is available about its accessibility to the public, its current use (visits, rental, etc.), or possible artifacts discovered on site. The data are limited to its legal protection and its administrative location in the Jura, Burgundy-Franche-Comté. Future research could refine this knowledge, including its specific archaeological context.
