Les Trois Pierres dolmen

Nestled in the heart of Saint-Nazaire, France, Les Trois Pierres dolmen, also known locally as Dolmen des Trois Pierres, stands as a testament to the region's rich prehistoric heritage. This intriguing megalithic structure, situated just 400 meters west of the bustling port and about a kilometer southwest of the train station, offers a captivating glimpse into the ancient past amidst the modern urban landscape.

The Historical Significance of Les Trois Pierres Dolmen

The history of Les Trois Pierres dolmen stretches back to a time when the area was a focal point of prehistoric activity. The first known mention of the site dates to 1679, in a declaration by the seigneur of Marsaint. This document describes the dolmen as a location where the prior of Saint-Nazaire was required to present his dues on Christmas Eve. By the 19th century, the dolmen had become a subject of interest for historians and archaeologists, appearing in various publications and even on the 1829 cadastral plan.

Originally part of the enclosed grounds of the Saint-Jean-Baptiste priory, the dolmen was sometimes referred to as the Dolmen du Prieuré. Over time, it acquired other names, such as the Dolmen de la Métairie or Dolmen du Bois Savary. The name Dolmen des Trois Pierres was introduced by Alain de Bizeul, highlighting the structure's distinctive trilithic form.

Exploring the Structure

The dolmen is composed of two upright stones, known as orthostats, supporting a massive horizontal capstone. This trilithic arrangement is a classic example of megalithic architecture, reminiscent of the impressive dolmens found in the Anjou region. The northern orthostat stands at 1.94 meters tall, while its southern counterpart measures 1.90 meters, with the capstone stretching 3.45 meters in length and weighing an estimated 7.5 tons. Crafted from gneiss with a schistose tendency, these stones have withstood the test of time, bearing witness to countless generations.

The Menhir and Other Megalithic Elements

In addition to the dolmen, the site features a menhir, a standing stone made of granulite. This menhir, which was re-erected in 1928 by Marcel Baudouin, measures over 4 meters in height, with 3.30 meters visible above ground. Baudouin also noted small cup marks and notches on the stone's eastern face, adding to its archaeological intrigue.

Several other stone blocks were discovered during Baudouin's restoration efforts, though only two remain today. These blocks, possibly remnants of the original structure, add to the mystery and allure of the site. One block, positioned near the northern orthostat, measures approximately 2.20 meters in length, while another near the southern orthostat is 1.30 meters long.

A Journey Through Time

The authenticity of Les Trois Pierres dolmen has been a topic of debate over the years, with some questioning its ancient origins due to the various alterations and restorations it has undergone. However, historical records and early illustrations affirm its longstanding presence in the area. In 1889, the dolmen was officially classified as a historic monument, ensuring its preservation for future generations.
