Björk got her Vegvísir tattoo in 1982 when she was 17 years old, at the first tattoo shop in Iceland. She later explained that she chose the symbol to keep herself from getting lost

The Vegvísir is an Icelandic symbol that translates to “sign post” or “wayfinder,” traditionally used as a protection charm. It appears in an old Icelandic book of magic and was believed to guide the bearer safely through storms or bad weather.
