In the small village of Ramil at the foot of the Camino, just before Triacastela, stands one of Galicia's most beautiful century-old chestnut trees. Its trunk spans 8.5 meters and, with its hollow spaces and thick branches that seem to embrace the tree, resembles an X-ray of time.

Large deciduous tree that is common in the mountains of Galicia. The fruits are covered with a green rind with thorns, the "erize". The season for harvesting chestnuts is November, and in Triacastela and throughout Galicia in general it is celebrated with a festival called "magesto". The main use of the chestnut tree is to obtain its wood and use its fruit as food for the population in general and as food for livestock.
