Yew tree of Pastur Nature · Illano, Eo-Navia, Asturias Image of Illano, not of the place itself. A yew in the hamlet of Pastur declared a natural monument on 13 March 2003; it measured 17.5 metres in height and 20 metres across the crown before a storm split half the tree away in January 2009, after which it was consolidated.
