The Meridian Gate (Manchu: Julergi dulimbai duka) is the southern (and largest) gate of the Forbidden City. It has five arches. The three central arches are close together; the two flanking arches are farther apart from the three central arches. The center arch was formerly reserved for the Emperor alone; the exceptions were the Empress, who could enter it once on the day of her wedding, and the top three scholars of the triennial civil service examinations, who left the exams through the central arch. All other officials and servants had to use the four side arches. The Forbidden City, built between 1406 and 1420, served for 500 years (until the end of the imperial era in 1911) as the seat of all power in China, the throne of the Son of Heaven and the private residence of all the Ming and Qing dynasty emperors. The complex consists of 980 buildings with 8,707 bays of rooms and covers 720,000 m2 (7,800,000 sq ft).
