Ephesus, for one.
Says who and what's their source proof? Wait....I think I found it.
"The house was discovered in the 19th century by following the descriptions in the reported visions of Blessed Anne Catherine Emmerich (1774–1824)"
On, and there is this. "The Catholic Church has never pronounced in favour or against the authenticity of the house."
Well there you have it. The concrete evidence!!! Right?
