A little history of this temple. The Temple of Heaven was built in the Ming Dynasty (AD 1420) by the emperor Zhu Di in the royal garden. Once a year, at winter solstice, the emperors came here to worship Heaven and to solemnly pray for a good harvest. Every year there are a lot of tourists visiting this temple. We went there in December and still lots of people doing the Tai chi. The park is quite huge you can spend more than 3 hours just walking around there. The temple of heaven is amount the top sites to visit in Beijing. The temple itself is really impressive and is typical from the ancient Chinese architecture.
