A Mammoth Mossy Beech Tree of Ponthus', Bretagne France

This particular tree is a legend by himself. He even has a name: Ponthus' beech. He lives in the Brocéliande forest, in Bretagne (France), the one where many Arthurian legends occurred. One can also find Merlin's tomb here (well, at least one of them...). Different stories exist, but a common one is that Ponthus, a knight of the round table, lived in a castle there, somewhere around the 10th century. He was disappointed by the fact he had no child, and blasphemed about it. God punished him by destroying his castle in a storm, and the tree grew on its ruins.
