The place where the emperors of the Ming and Qing dynasties worshiped the god of the moon, the god of the night light

"Yuetan Park" is located west of Nanlishi Road and south of Yuetan North Street in Beijing. Originally named: Xiyue Altar, it is one of the five altars in Beijing. It was built in the ninth year of the Jiajing reign of the Ming Dynasty (1530) and was the place where the emperors of the Ming and Qing dynasties worshiped the god of the night light (the moon) and the gods of the stars in the sky on the autumn equinox. At the end of the Qing Dynasty, the activities of worshiping the god of the night light were abandoned, and Yuetan fell into disrepair. In 1955, Yuetan was converted into a park, which is divided into two parts: the South Park and the North Park. The North Park is characterized by ancient buildings with red bricks and green tiles and regular roads, while the South Park is composed of rocks, ponds, and winding paths, forming a natural landscape garden.
