The egg shape seeks to symbolize rebirth and new opportunities at the start of Kiruna’s urban transformation, a project that involves the relocation of entire city districts in response to ground subsidence caused by decades of iron ore mining. The temporary and traveling egg-shaped sauna is covered in stainless steel mirrors with titanium, gold-colour coating. It is only five meters tall and accommodates a handful of punters. Its interior is made from pine and aspen, and the sculptural oven in the center has been webbed from local iron and stones.
