Dowlatabad Garden Wind Tower, Yazd

The world's tallest adobe wind catcher (badgir) at 33.8 meters — the pinnacle of Persian passive cooling technology, standing in the Dowlatabad Garden of Yazd. The hexagonal tower is aligned to capture prevailing winds and channel them through internal baffles to cool the garden pavilion below. Combined with qanat-fed underground water channels, the system produces temperature drops of 10-15°C without any mechanical input. The garden follows a NW-SE axis, and the six-fold geometry of the tower creates aerodynamic properties that accelerate airflow. Part of the UNESCO-inscribed Persian Gardens (2011), which recognized the chahar bagh tradition as one of humanity's great contributions to landscape architecture.
