Xu Tiantian DnA_Design and Architecture Beijing Jinyun Quarries : the quarry as a stage : from economic exploitation to ecological reuse Zusammenfassung: In 2021 the Beijing architect Xu Tiantian and her firm DnA_Design and Architecture were awarded a commission to develop new utilization concepts for the old and today abandoned stone quarries in the northern part of Jinyun County in Zhejiang Province. Located in direct proximity to Songyang where Xu Tiantian has already very successfully realized revitalization projects for the rural area which have received close international attention are over 3000 disused small stone quarries that until recently were still mined manually. The nine stone quarries that have been worked on by Xu Tiantian and her team since then are located in a valley named Xiandu with an impressive natural landscape and bizarre volcanic rock formations that is already a tourist attraction today. To support the development of the region with the measures the project strives for ecological improvements while simultaneously creating social and cultural locations to be used by both the local population and visitors. The converted stone quarries that have been given a new use are part of a public infrastructure that puts historical aspects going back over a thousand years as well as the everyday cultural heritage in a new context.
