The Dowlatabad Garden Wind Tower, Yazd is a thirty-three-metre badgir on the grounds of the Dowlatabad Garden complex in Yazd, central Iran — the tallest standing example of traditional Iranian wind-catcher architecture. The garden was commissioned in 1747 by Mohammad Taqi Khan Bafqi, regional governor for the Zand dynasty, and the tower is integrated into the main pavilion's central reception hall. The eight-sided badgir captures prevailing desert winds at altitude, channels them downward through internal partitioned shafts, accelerates them by Venturi effect, and discharges the cooled air across a small interior pool to evaporate and chill the room below. The whole pavilion is supplied with water from a qanat originating roughly 65 kilometres away. The Dowlatabad Garden was inscribed on UNESCO's World Heritage list in 2011 as part of the Persian Gardens serial nomination.
A pre-electric air conditioner sits over a pre-industrial water main, and both still work.
