Originally, the Temple of Heaven was called Temple of Heaven and Earth, because it was built according to the Temple of Heaven and Earth in Nanjing, the early Ming capital at that time, so both heaven and earth were worshiped here. In 1530, another structure, the Temple of Earth was built in the northern part of Beijing and then Heaven and Earth were worshipped separately. Since only Heaven was worshipped here, it was renamed the Temple of Heaven. Since 1421-1530, over a hundred years or so, there were altogether 9 emperors of the Ming Dynasty who held the worshipping ceremony of both heaven and earth for over a hundred times. During the Ming and Qing dynasties, the Temple of Heaven was the place where the emperors came to worship the God of Heaven and prayed for a good harvest.
