A topic chosen looking at the geographic and historical trates characterising the village of Stenico (in the region Trentino Alto Adige, Italy) and the original function of its castle as a secure place for locals. A theme that encourages artists to reflect upon the stratification of local civilization, a phenomenon that in history of Giudicarie Esteriori is deeply linked to the relationship between human beings and the natural environment surrounding them. A shelter which includes all creatures inhabiting the forest, thus not limited to human beings. Participation categories Artists may choose to participate in one of the following categories: 1. Installation made using natural, local material, and placed in an assigned location alongside the trail. The organizing association, in collaboration with the artist, is open to provide extra material if needed, on the condition that it is of natural origin. 2. Sculpture, made working on a vertical trunk of pine from Val di Cembra (Trentino, Italy) measuring 2 meters in height and between 40 and 45 centimeters in diameter, planted on the ground. All artwork will remain on site at the end of the event and become property of the organization. Artists are kindly invited to work during daytime, between 10 and 18, in order to allow a contact with the public. Sculptures and installations represent different but dialoguing parts of a 1400 mt long ring trail, in which artwork is meant to be integrated with nature, thus bound to get enriched by the flow of time and change of seasons.
