Alignements du Gueldro

The Gueldro alignments are approximately one hundred standing stones arranged in several long rows across a coastal area in southern Brittany. These formations display the construction techniques and organizational methods used by Neolithic communities to move and position massive blocks.

The stones were erected during the Neolithic period, likely thousands of years ago, serving ritual or navigational purposes for ancient populations. Official recognition came in 1963 when the French government protected the site as a classified historical monument.

These rows shaped how ancient people organized their sacred spaces and marked important paths across the landscape. Walking among the stones gives you a sense of how communities once moved through and used this coastal region.

The site is easily reached from the main road passing through Plouhinec village. Wear sturdy shoes, as the terrain is uneven and the stones sit directly on the ground surface.

The original arrangement of the stones has been altered by damage and relocations, particularly when carriers broke some stones and others were moved for road construction in the early 1900s. These changes highlight how vulnerable such ancient structures can be and why protection became necessary.
