The mansion is owned by Solomon Goldsmith. It is located in France. After Diva awakens from her hibernation, she is first taken to her favorite chevalier Solomon's house.

The outward appearance of the mansion is never shown in the anime. The only interior feature that is displayed is the monumental scale garden inside the mansion. It is encased in glass panels like a giant greenhouse. There is a dining arrangement in the middle of the garden like place. The place has also skeletons of prehistoric animals as well as a genetic tree engraved onto the surface.
