Tiananmen was built in the 15th year of Yongle in the Ming Dynasty (1417 AD). It was originally named "Chengtianmen", which means "carrying the destiny of heaven" and "mandating from heaven". ; means, the side view of Tiananmen is the main entrance of the Forbidden City. At that time, Chengtianmen was far less magnificent than Tiananmen. It was just a three-story wooden archway with a plaque of "Chengtian Gate" hanging in the middle of the archway. This building was destroyed by fire in 1451 AD, rebuilt in 1465, and destroyed by war in the late Ming Dynasty. It was not until the eighth year of Shunzhi in the Qing Dynasty (AD 1651) that it was rebuilt, and it generally became what it is today, and was renamed "Tiananmen". .
