Origin and history

Roch'an Evned is an archaeological site located in the commune of Ploubazlanec in the Côtes-d'Armor department of Brittany. This monument, dated from the Prehistory and more specifically from the Neolithic, illustrates the techniques of fortification and occupation of the territory by ancient populations. Its strategic location on a promontory suggests a defensive function or control of local resources, typical of sites of this period.

The promontory was recognized for its heritage importance and was classified as historical monuments by an order dated 7 January 1959. This classification attests to its archaeological value and the need to preserve this vestige of the first human occupations in Brittany. The site is now owned by the Côtes-d'Armor department, which guarantees its conservation and study for future generations.

Available sources, including databases such as Mérimée, precisely locate the site at the place called Roch'an Evned, at the approximate address of 3 Rue de Landeris in Ploubazlanec. Although architectural details or archaeological excavations are not explicitly described in the sources consulted, the legal protection of the site allows us to consider future research to better understand its role in the Breton Neolithic context.

In the Neolithic era, barred promontories were often used as places of refuge or assembly by local communities. These sites were used to control land and sea access while providing natural protection against intrusions. In a region such as Brittany, where coastal resources (fishing, salt, sea trade) played a major economic role, these promontories could also serve as monitoring points or symbolic places for sedentary populations.

The absence of specific records of excavations or artifacts discovered at the Roch'an Evned site limits the detailed knowledge of its occupation. However, its ranking among historical monuments underlines its interest in understanding the social and territorial dynamics of Neolithic in Brittany. The barred promontories, more broadly, reflect a pivotal period in which human societies move from a nomadic lifestyle to a more sedentary and structured organization.

Today, the promontory of Roch'an Evned remains a silent but precious testimony of this distant time. Its state of conservation and accessibility (although not specified in the sources) could make it a site of interest for archaeology and local history enthusiasts, subject to the regulations in force for listed monuments.
