While the interiors would need to be done, and perhaps change the building exteriors back 500 years, I have to believe that JK or the other epic city modders could take this file: https://sketchfab.com/3d-models/mont-saint-michel-france-ee4eb76e449044d297010c49a178825a and quickly build an epic location.  They only want attribution, which is de rigeure in this community.
