I've been searching and searching for actual Gilles shrines and I haven't come up with anything. In this website below it mentions where Gilles was executed but upon searching through the website for Chateau Ducal (which now holds a bunch of museums) there was no mention of Gilles again, which leads me to believe that they do not have any shrines or monuments of him.
Chateau Ducal
The original seat of the counts of Nantes and later the Dukes of Brittany, this fortress is steeped in history. Within its walls many, like the Duchesse of Berry, were imprisoned or, like Gilles de Rais, were executed.

Will keep searching
From the Gilles de Rais wikipedia article:
ReplyDeleteSeveral years after Gilles' death, his daughter Marie had a stone memorial erected at the site of his execution. Over the years, the structure came to be regarded as a holy altar under the protection of Saint Anne. Generations of pregnant women flocked there to pray for an abundance of breast milk. The memorial was destroyed by rioting Jacobins during the French Revolution in the late 18th century.
