Aegna Island Labyrinth, Tallinn

A partly preserved stone labyrinth on Aegna island near the Estonian capital Tallinn — a small forested island in the Gulf of Finland that has served as a military fortification since the Russian Empire. Aegna's labyrinth, though damaged, represents the Baltic labyrinth tradition's southeastern reach. Tallinn's medieval Old Town (a UNESCO World Heritage Site) sits just across the bay. The Gulf of Finland labyrinths on both shores — Estonian and Finnish — suggest a shared maritime ritual culture spanning this narrow but significant waterway. At Giza bearing 353.53°.
