Chaoyang Gate (the Gate Facing the Sun) was the main gate in the east of the city through which grain from the Grand Canal was shipped to the granaries inside Chaoyangmen during imperial times. The gate was demolished, along with the walls and moat in the 1950s to make way for the 2nd Ring Road, together with an elevated roundabout where the original gate had stood.
Chen Ruoju and Zhou Lingzhao of the Academy of Fine Arts, Ceramics Department, at Tsinghua University were responsible for these ceramic reliefs
Exits G and H from the station both feature an attractive glass wall made up of a repeated photo of Chaoyangmen in its heyday.
(This is what it used to look like...)
