Not too many k's from where we live is this old mansion. It's called Mintaro. We didn't have it in mind for Greyfallows, because we didn't even know it was there! It's just been placed on the market after the death of its owner.
Have a look at the photos--marble walls and ceilings, carvings, painted frescoes. How beautiful it is! It'll give you some idea of how we imagine "Greyfallows".
