Tips from the Community

Julien Harté
November 15, 2025, Cairn dit Château Bû

The cairn known as "ChâteauBû" in Saint-Just is an ancient megalithic site comprising a passage grave and a 46-meter-long stone tumulus. Excavations have revealed Bronze Age burials, and four quartz menhirs stand atop the tumulus.

A "treidelpfad" (towpath) that runs alongside the river or canal's bed was an essential part of the transport infrastructure in earlier times. Before ships could be powered by motors, horses walked along the bank, pulling the boat against the current. This was called "treideln" (towing), and this is how the towpaths got their name, which has been passed down to this day. Where these paths, located directly along the bank, have been preserved, they are popular with hikers and cyclists.

This path which runs along the banks of the Vilaine was built in the 18th century. At the time, it allowed barges to be pulled, most often by horses. It now allows you to cycle or walk in complete peace of mind!

The menhirs of Brittany are large, mostly solitary monoliths erected by the people of the Megalithic culture, some of which were later toppled or repurposed. The Neolithic Megalithic culture reached its peak between 4500 and 2500 BC. With some dating back to around 4000 BC, these monuments are significantly older than, for example, the Egyptian pyramids, which were built around 2500 BC.
