Badgir, Windcatchers of Ancient Persia

Persian Culture, wind catchers of ancient Persia, dating from the 1st millennium B.C.E., still in use; the towers scooped air and released air to ventilate and cool the living spaces on ground floors and basements in buildings; through the screens on top of the tower, dry dessert air is pulled downwards through wetted meshes, reducing the air temperature by 10 deg. F (12 deg C).

Material: Stone, unfired and fired brick and wood.
