End of day brings beautiful lighting. The Holy Grail is said to have been kept there, as the faithful fled the Moors, see account that stories produce, at http://thespiralofknowledge.com/dossier.cfm?lang=en&id=49.
Holy Land, to Huesca, and then circuitous protection route beginning in the 8th Century with the Moorish invasions, with, some say, final arrival at Valencia.
Start at the foot of Mount Pano, above the old town church, Santa Cruz de la Seros, and up the mountain. The cliff monastery, San Juan de la Pena, is in two parts -- the older cliff monastery, and a newer and large one at the flat summit.
There are other traditions or origins, in addition to the Holy Grail at San Juan de la Pena, see http://www.hikepyrenees.co.uk/san-juan-de-la-pena.html. It is said that a nobleman was hunting, chased a stag who leaped off a cliff, the nobleman and his horse followed. The nobleman prayed for deliverance on the way down. Sure enough, he landed at a cave, found a hermit's bones inside, and gave thanks and built the monastery. San Juan: Saint John. Which?
Route note: after Roncesvalles, the logical next stop would Pamplona. We had already seen the bulls running there, so took the bypass. Pamplona: see http://spainroadways.blogspot.com/2008/02/pamplona-bulls.html/
