Here in Florida, we have the “Mary, Queen of the Universe” shirne for all the Catholic toursit in the Orlando area. Just from the name, it seems to be all about Mary and only incidentally about Jesus. “Queen of the Universe” seems to be a rather grandiose offshoot of the more typical “Mary Queen of Heaven”, The problem with that is that the only biblical mention of a “Queen of Heaven” is in Jeremiah and it’s not at all falltering. With Jesus being King of Kings and Lord of Lords there’s no real need for a queen.
Constantine as emperor seemed to be ok with his mother investigating the Christian religious sites. She wasn’t a queen, but she got a lot of the pilgrimage sites onto a lucrative path.
Egypt is probably the worlds record holder for a tourist attraction continuously operating in the same location.
Stonehenge might give it a bit of competition though.
