Count of Toulouse, Margrave of Septimania (Narbonne).

"A beautiful Villa in the south of France"
Saint Guilhem le Desert
Saint Guilhem was the man who gave his name to the beautiful monastery in the Gellone valley, 30 kilometres northwest of Montpellier. Born sometime in the late 8th century, Guilhem was the grandson of Charles Martel, the Duke of Aquitane, and one of the Emperor Charlemagne's chosen knights. He fought bravely against the Saracens of Spain and became famous as the hero of medieval ballads of knightly prowess and chivalry. A devout Christian who ended his days (died 812 AD) in the monastery at Gellone, he endowed the abbey with a relic of the True Cross, given to him by Charlemagne.
