Underneath Søndermarken in Frederiksberg lies an astonishingly large, high-ceilinged space with columns, puddles and dripstones everywhere. Built in the 1850s to provide a solution for Copenhagen’s drinking water problems, the Cisterns are today an exhibition venue for contemporary art. For the last three years, the exhibitions have been created to integrate and utilise the distinctive architecture and atmosphere of the venue. This spring, summer and autumn,the unusual exhibition space, which is also Denmark’s largest dripstone cave,is used to show That Dream of Peace by Eva Koch, an experimental Danish artist working in the fields of video installation, sound and sculpture.
