Natural Monument, one of the eight existing in Galicia. This forest, with an area of 45,185 square meters, has exceptional specimens of oaks and chestnut trees, some of the latter reaching 30 meters in height and 5.5 meters in circumference, and are considered to have the highest growth rate in Europe. It was owned by the Quiroga family, inhabitants of the manor located in the place of the same name, a few meters from the forest, which is why it is also known as “Fraga de Quiroga”, “Souto de Quiroga” or “Carballeira de Quiroga”. In 1864, one of the descendants of this family married Emilia Pardo Bazán, who later, perhaps in this palace, wrote some chapters of her work “Os Pazos de Ulloa”. In the mid-20th century, the FAO (Food and Agriculture Organization of the United Nations) demanded the protection of this forest. In 1998, it became the property of the Ministry of Agriculture and Environment, being declared a Natural Monument in the year 2000. It is possible to enjoy the forest by following a simple and short circular marked trail, only 1,200 meters long, equipped with interpretive panels.
