The tree's age is estimated to span roughly 1,000 years, making it a contemporary of the early medieval period in Brittany.
The hollow center of the trunk is large enough to have historically concealed a human adult.
It received the 'Remarkable Tree of France' label in 2000, confirming its status as a protected natural monument.
The tree is located near the village of Concoret, known for its focus on the preservation of Brocéliande's folklore and biodiversity.
The Chêne à Guillotin (Guillotin Oak) is a peduncular oak tree located in the Brocéliande forest, estimated to be between 800 and 1,000 years old. It stands nearly 20 meters tall with a circumference of approximately 10 meters at the base. The interior of the trunk is hollow, allowing visitors to glimpse the massive internal cavity that characterizes its advanced age. It is recognized as one of the oldest living trees in Brittany and is classified as a 'Remarkable Tree of France.' The tree is named after Abbé Guillotin, a priest who allegedly used the hollow trunk as a hiding place during the French Revolution. Access is provided via a managed path through the woodland setting of the Paimpont forest. It remains a focal point for regional heritage and forest conservation efforts.
