Located on a spur of Armorican sandstone, overlooking the Trun plain, Camp de Bierre is one of the largest and most spectacular archaeological sites in western France. The scale and level of preservation are extraordinary: the main dry-stone wall measures 32 metres across and 7 metres in height. Through the story of the site - uncovered by archaeologists - you can travel back in time to the Neolithic era (around 3,500 BC), the date of the oldest known human occupation, via the Gallo-Roman, iron and bronze ages.
