This ‘contemporary’ grotto is located on the shores of the St Mary’s River in Sault Ste Marie. The design weaves a series of diverse elements into a coherent story of Sault Ste Marie and its relationship with Saint Mary. Three walls, composed respectively of indigenous trees, stacked I-beams and curving sandstone meet under a canopy sheltering a statue of Mary. The indigenous trees evoke the pre-history of the city while the sandstone witnesses its period of building. Stacked I-beams serve to reflect the importance of steel making to the local economy.
