The tree of Gernika (Guernica in Spanish) is one of the sacred trees under whose shade the custom developed–and continues–that representatives assembled. The significance seems to have pagan or pre-Christian origins. These trees have a history representing various deities whose names appear on gravestones such as in Aquitaine Arixo deo (“God Roble”); Arteche deo (“God oak”). While there are several revered oak trees (e.g., the Malato in Luiando, tree Krutzia, the Sobrarbe, the Aretxabalagañe that of Abellaneda, Gerediaga oak of Durango, etc.), it is the one in the Basque town of Gernika that has gained wider significance as the modern symbol of Basque freedoms.
