Megalithic architecture in western Europe is one of the most remarkable phenomena of the era.

Two different types of tomb appeared in this era. The first were enclosed tombs and those in Carnac were quite monumental, each containing a single deceased body along with a range prestigious items. These tombs are known as the Carnac Tumulus.

A few centuries later corridor type burial mounds known as dolmen (stone tables), or collective burial chambers began to appear. Today, only their structures are still visible.

The standing stone alignments played a more symbolic role.
A series of displays in the museum make it possible for visitors to understand how megalithic architecture developed and changed from 4500 to 2000 BC.

Engraved stone slabs and casts from several dolmens show the variety of the representations, whether symbolic or figurative including axes, crosses and abstract motifs for example. There are different possible interpretations of these signs.

The neolithic age was a crucial stage in the development of mankind. Previously, nomadic hunter-gatherer, men in this era began to settle become sedentary. Man began to farm and breed animals. New technologies appeared. In the museum room dedicated to everyday life, each in turn the displays give visitors information on farming and animal breeding, ceramics, carving flint, stone polishing, jewelry items like the green stone (known as callaïs), polished axe-heads or even rings and disks.
