The Imperial Granary faces towards south. It is 22.9m in width, 16.9m in depth, 9.9m in height and occupies 500 square metres, supported by 8 columns dating back to Ming dynasty reinforced with modern steel. The wall is 1.5m in thickness. The Granary serves as crop storage for the imperial household and the royal guards and thus is built in the class of military defence, which ensures its endurance.
Furthermore the Granary employs state-of-the-art ecological technology of ancient China. Location on a higher terrain enables efficient drainage underground while the thick wall with vent guarantees nice draught and consistency in room temperature.
