Oñati, municipal area in which Arantzazu is located, is a land of strong historical character and home to historical monuments, its incommensurable nature being the most valuable of them all. Made up mainly of sandstone and limestone rocks, the landscape offers a complete repertoire of related shapes; caves, peaks, dolines, limestone pavements… The underground networks, like Gesaltza-Arrikrutz, are of extreme significance to the Basque Country, reaching extraordinary lengths, depths and extensions and forming a true paradise. Some of the hollows were inhabited a long, long time ago, generating a long thread of superstitions and beliefs. The flocks, the pastures, the beech woods, the limestone walls, the ravines and the peaks compose a symphony of extraordinary beauty, which the griffon vultures observe, soaring up in the skies, while the sheep and horses sift through every square mile, rollicking ceaselessly.
