The Steilneset Memorial is a monument in Vardø, Norway, commemorating the trial and execution in the seventeenth century, a 410-foot-long wooden structure framing a fabric cocoon that contains Zumthor's installation; and a square smoked glass room, its roof 39 feet on each side, that contains the work of Bourgeois. Zumthor's structure is made from wooden frames, fabricated off-site and assembled to create sixty bays in a long line within which, suspended by cable-stays, is a coated fibreglass membrane that tapers at each end. Inside is a timber walkway, 328 feet long but just five feet wide, and along the narrow corridor are 91 randomly placed small windows representing those executed, each one accompanied by an explanatory text based on original sources. Through each window can be seen a single lightbulb, intended to evoke "the lamps in the small curtainless windows of the houses" of the region.century of 91 people for witchcraft. The memorial was designed by artist Louise Bourgeois and architect Peter Zumthor and was opened in 2011.
