Near the ice-house lake, it is possible to visit the blockbau wooden reconstruction of the Smoke sauna prototype planned by the Finnish architect Alvar Aalto for his experimental house in Muuratsalo (Finland). It was built between 2003 and 2005, during three work-camps held for the students of the Degree Course in History and Conservation of the Architectural and Environmental Heritage coming from various European universities, according to the traditional Finnish wood processing techniques, under the technical direction of the Finnish carpenters and with the collaboration of the local workers.
The creation of a smoke sauna in Val di Susa may seem alien to the local culture and environment but, within the context of the Ecomuseum, it acquires an important meaning of integration between different building cultures, above all as far as traditions, technologies, and tools used are concerned.
