“The buildings on the palace complex include a house with an area of 17,700 m², an arboretum, a greenhouse, a helipad, an ice palace, a church, an amphitheater, a "tea house" (guest house), a gas station, an 80-meter bridge and a special tunnel inside the mountain with a tasting room.” I’ve not heard a bunker called a Tasting Room before. So I guess Lanfranco Cirillo has a copy of the plans and building details, that could come in handy.
