This historic oak was born at the time of Enlightenment. He was a witness in 1856 of the Democratic Banquet of Conxo, a revolutionary act that vindicated the ideals of the new Europe: Liberty, Equality and Fraternity. It was defended by Rosalía de Castro in a pioneering ecological protest in Spain. And the forest that welcomes it, at the foot of the Portuguese Pilgrimage Trail, is today a whole botanical treasure chest, open to the public in 2018 (with a great popular festival) after remaining inaccessible for more than a century.
