Located behind Tiananmen Square is the southern and main entrance to Forbidden City. The name Meridian Gate is derived from the word for the longitudinal circle around the earth. Emperors believed they were the Sons of Heaven and therefore should live at the center of the universe. In Chinese, it is called Wumen. This impressive structure with five towers – this central one is tallest at 124 feet – was part of the original construction ending in 1420. Feel privileged when you walk through the middle of its five portals. For hundreds of years, this entry was reserved for the emperor. The empress was only allowed to walk along Imperial Way on her wedding day.
