The Periscope Tower is a giant wooden periscope structure that serves as an observation tower and engages the viewer ina dialogue with the landscape. With the help of a large mirror the Periscope Tower makes it possible for everyone to enjoythe views of the surrounding landscape. One can either climb up the stairs to enjoy the view over the lake and into thesurrounding landscape from the viewing deck, or simply stay on the ground and get the view through the periscope mirror.Made entirely of wood, the building is composed of an inner core of cross laminated timber (CLT) and an external wooden frame that serves as a load bearing structure. The inner core made of CLT forms the frame for an extra large periscope with stairs circling around it. When taking the stairs up or down one can experience a rich range of different views framed by the various openings cut into the structure.
