The “sobreira” or cork oak is a tree that belongs to the Mediterranean climate and is recognised by its thick and spongy bark. As well as giving excellent timber, it is from the “sobreiras” that the bark is used to make corks.
The cork oak that is of interest here is in the village of Santiorxo, in the parish of Liñares and is officially recognised as an “Árbol Singular” unique tree of Galicia because of its special characteristics.
This is a hundred year old tree with a diameter of almost 3 m. and a perimeter of 10.8 m. These surprising dimensions are due to a disease that affects it and that caused the trunk to perforate in the middle.
