Imperial City Wall Relics Park, Urban park in Dongcheng District, China.

The Imperial City Wall Relics Park is a green corridor in Dongcheng that follows the line of a historic fortification and features expansive lawns, dense plantings of shrubs, and diverse vegetation throughout. The park has a linear structure with water features and sculptural works integrated into the landscape design.

The park was established in 2001 to preserve sections of the original Ming Dynasty wall that once surrounded the Imperial City in Beijing. The project transformed the wall's remains into an accessible green space that protects these historical foundations.

The park's name, Huangchenggen, refers to the root of the Imperial City wall. During construction, workers excavated part of the Ming dynasty Dong'anmen gate and its inner stone bridge, which are now protected and displayed openly. A short section of the Imperial City's east wall was rebuilt on its original site to mark its position and form.

The park is near popular shopping areas and easily accessible through nearby subway stations, making it convenient to visit between other activities in the city. The green space is open during daylight hours and works well for a quick walk or longer stroll.

The park is 2.8 kilometres long but only about 29 metres wide. During construction, workers unearthed the remains of the Ming dynasty Dong'anmen Gate and a stone bridge inside it; both are now protected and displayed openly. A short section of the Imperial City's eastern wall was rebuilt on its original site to show its former position and form.
