The Daming Palace was the imperial palace complex of the Tang Dynasty, located in its capital Changan. It served as the residence of the Tang emperors for more than 220 years. Today, it is designated as a heritage site of China. The area is located northeast of present-day Xian, Shaanxi Province, the palace was originally known as Yongan Palace, but was renamed to Daming Palace in 635. In 662, after renovations to the palace, it was renamed to Penglai Palace, in 670, it was named to Hanyuan Palace or Yuan Palace. Eventually, in 701, the name of the palace became Daming Palace again, at the founding of the Tang dynasty in 618, the Taiji Palace, built in the previous Sui dynasty, was preserved as the imperial residence. Its north entrance was the site where prince Li Shimin killed two of his brothers, including the prince, at the bloody palace coup known as the Xuanwu Gate Incident in 626. The same year, he was crowned as Emperor Taizong, as his father Emperor Gaozu yielded him the throne, according to him, ever since Emperor Taizong moved to the countryside during the summers, his retired father was left behind in Changan to suffer in the summer heat. However, his father would always decline any invitation to spend the summer together when Emperor Taizong eventually did invite him. Ever since the palace coup of the Xuanwu Gate Incident in 626, it seemed that father. In 634, Emperor Taizong launched the first construction of the Daming Palace at the Longshou Plateau and he intended to build a small-scale summer palace for his retired father, Emperor Gaozu, as an act of filial piety. However, Emperor Gaozu fell ill, and died in 635, the Tang dynasty underwent rapid development under the diligent rules of Emperor Taizong, and his son Emperor Gaozong.
