Just north of Beijing, between the Great Wall and Yanqi Lake, the Xingfa Cement Plant once fueled China’s construction boom, operating for over two decades before its 2015 closure under the National Air Quality Action Plan. Today, an adjacent quarry that once provided raw materials has been remediated as a 107.5-hectare terraced park that anchors an accompanying 17-acre research campus on the site of the plant.
Where a single willow tree once stood, the valley now supports a vast, layered network of emergent plant communities selected to adapt in rocky, alkaline soils. Native arborvitae stabilize slopes and retain moisture through summer droughts. Legume-producing species enrich the thin soil, while seasonal stands of smoke tree, mulberry, and elm provide canopy and seasonal color. Invasive plants introduced during the site’s industrial era have been cleared and replaced with species that restore soil conditions. On the southwestern end of the site, a seasonal pond has been added to retain stormwater runoff and reduce erosion across the exposed quarry floor.
Paving, walls, and trail edging were constructed using recycled stone and shale. Salvaged conveyor housings and other industrial remnants were embedded into the landscape along the “Trail of Memory,” a pedestrian spine linking the two quarry pits that pays homage to the site’s industrial past. Climbing up a nearby hilltop to an overlook pavilion, a 1.2-kilometer hiking trail provides panoramic views of the surrounding Yan Mountains.
Polliwog Park
Originally built in the 1970s, Polliwog Park is a high-use neighborhood amenity that provides active recreation and play facilities to local families. The original playground was replaced in 2003 but required a full update in 2020 to account for routine flooding. SWA’s design allows the park to remain an active community feature year-round.
