It is said that there is an ox skin full of gold in Erreberentzileku, on a slope next to the church of San Gregorio; but it is so shallow that it would be possible to unearth it with a goat’s hoof. Another ox skin is also hidden in the headland between the roads of Larburu and Urkullaga, so high that it can be unearthed with a sheep’s hoof.
