The Temple of Heaven in Beijing was constructed between 1406 and 1420 during the Ming Dynasty as the site of imperial ceremonies and prayers for good harvests. The complex covers over 2,700,000 square meters and includes three main structures - the Hall of Prayer for Good Harvests, the Imperial Vault of Heaven, and the Circular Mound Altar. The buildings are arranged according to Feng Shui principles and feature ornate woodwork, blue tile roofs, and designs that represent the relationship between heaven and earth. Today, the Temple of Heaven is one of Beijing's most popular tourist destinations and a prime example of imperial Chinese architecture.
