The Forbidden City, also named the Palace Museum, shares the honor of being one of five world-famous palaces with the Palace of Versailles in France, Buckingham Palace in England, the White House in the U.S. and the Kremlin in Russia. The palace, the most magnificent and splendid palace complex in China, was listed as a World Cultural Heritage Building in 1987. It was built in the Ming Dynasty (1368-1644) and the construction of this group of buildings took fourteen years from 1406 to 1420. In the Ming Dynasty and the Qing Dynasty (1644-1911), it was the imperial palace where twenty-four emperors ascended the throne and exercised their strong power to the nation.
The incomparable palace occupies an area of 720,000 square meters (177.9 acres) and has approximately 8,700 rooms. A high red wall with a total length of 3,400 meters (3,718 yards) encases the palace. There are four gates in each side, with Meridian Gate (Wu Men) as the main entrance. Four exquisite watchtowers sit at the corners of the wall. With roofs covered with golden glazed tile, red painted walls and grey-white bases, the rectangular palace appears extremely luxurious and grand. Spectacular halls in it are neatly arranged in bilateral symmetry along a central axis that conforms to the axis of Beijing City.
