Sandhamn Labyrinth, Stockholm Archipelago

A stone labyrinth on Sandhamn (Sand Harbor) in the outer Stockholm archipelago — historically one of Sweden's most important pilot stations, where ships waited for pilots to guide them through the treacherous approaches to Stockholm. Sandhamn has hosted the Royal Swedish Yacht Club since 1897. The labyrinth's placement at this maritime threshold — between open Baltic and protected inner waters — echoes the ancient tradition of labyrinths marking transitional zones between familiar and unknown seas.
