Saint Michel d'Aiguilhe – the Chapel Built atop a Volcanic Plug
Back in the year 951, a French bishop was celebrating his return from a major pilgrimage. It had taken Bishop Godescalc many weeks to go from his home of Le Puy-en-Velay in France to Santiago de Compostela, almost 500 miles away in Spain and on his return he decided to celebrate. On the route his pilgrimage took, he had visited many shrines and chapels and so he decided to build one himself so that future pilgrims could use it as their own starting point. As Le Puy had a remarkable geological feature – a volcanic plug 279 feet (85 metres) high, that must have seemed like a very good place indeed to build a chapel. Image Credit

Local chronicles show that at this time the town was being ravaged by plague, and the dean had vowed to Saint Michael the Archangel that he would build a chapel there if the plague ceased. It did and so, the vow was fulfilled. Whether Bishop Godescalc’s pilgrimage was also an attempt to alleviate the plague through prayer and penance on his journey has been lost to history, but it is these two men who we must thank for the chapel’s existence.
