Menhir de Guihallon

The Menhir de Guihallon is a Neolithic standing stone located in Lamballe-Armor. The stone is made of local gabbro rock and rises to around 5 meters high while measuring roughly 3.6 meters at its widest point.

This stone was erected during the Neolithic period and ranks among the oldest human structures in Brittany. French authorities officially recognized it as a classified historical monument in 1965.

This standing stone was placed by early communities to mark a meaningful location in their landscape. Such monuments helped ancient people define spaces important to their daily lives and beliefs.

This stone sits on elevated ground within the commune and is freely accessible from outside. Visitors can best locate it by exploring the area and asking for local directions.

The top of this stone leans noticeably backward rather than standing perfectly vertical. This unusual tilt has developed over thousands of years and sets it apart from many other standing stones.
