This is a domed room supported with stone arches, about 20 feet high in the center. The floor is natural stone except for a wooden disc about 3 feet in diameter in the center. To the west, a stout wooden door has been barricaded with a pile of barrels, bales, and odds and ends of broken furniture.
The wooden disc covers the cistern. There are two iron handles for lifting it from its niche. Below, the stone shaft of the cistern descends into the darkness to the water, about 25 feet below. The stone is rough, with gaps between the courses, making it relatively easy to climb (DC 8 Agility check to climb down or up without falling into the water below).
The cistern is sourced by a deep spring which provides a slow, constant flow of water. Excess water drains through a downward-sloping overflow tunnel (at water level) leading south to the koi pond (area 1-2).
If the PCs examine the stores used to barricade the western door, they can find a small cask of brandy and two amphorae of olive oil among the furnishings and bales.
