This article presents the emerging transdisciplinary practice of Experimental Heritage as performed within an ongoing Irish-Swedish research project involving artists and archaeologists. The project is undertaken simultaneously in western Ireland and south-eastern Sweden. It explores the chosen Irish and Swedish landscapes of Clare and Öland, their similarities and differences, with the aid of combined and integrated artistic and archaeological practices. The starting points for common explorations are: stone and water, movement and time/the multitemporal, and the tangible and intangible aspects of landscape experience. In a transdisciplinary process, we explore new ways of combining art, archaeology and heritage within and between these landscapes.
