Dissignac tumulus

The Dissignac tumulus is a Neolithic burial monument containing two interconnected burial chambers reached through narrow passageways. The structure is built from large granite and other stone blocks carefully stacked to form its underground chambers and protective mound.

This burial site was constructed around 4300 BCE during the Neolithic period, making it roughly 2000 years older than Egypt's earliest pyramids. It demonstrates that sophisticated stone building techniques appeared in Europe well before the rise of ancient Mediterranean civilizations.

The carved stone slabs inside the chambers feature engravings depicting axes, curved staffs, and other symbols from the Neolithic world. These markings offer insight into the beliefs and thoughts of those who created this burial place.

The site is located outside town and can be difficult to reach without prior planning. Check conditions and access arrangements ahead of your visit, as opening times and guided tour availability change throughout the year.

The monument was originally surrounded by three concentric enclosure walls built from local gneiss, creating a layered circular design. This unusual multi-layered approach suggests the builders had a deliberate architectural plan for the structure.
