Here is the history: the original owner and builder of the Villa loved to play cards and get drunk with his friends. When his wife objected to this taking place in the Villa, he built the small booze house next door.
The closeness to the Villa made it easy for him to find his way home. In addition, the booze house had a pit in the ground where he could store the drink in a cool place.
Today’s main purpose of the booze house is to look great on photographs.
