Koorküla Valgjärv Lake Settlement
Estonia's only known prehistoric pile settlement (muinasaegne vaiasula), with wooden structures from the 7th-9th centuries AD visible underwater at depths of 1-4 meters. The high water transparency allows direct observation of the remains — a unique window into pre-Christian Finno-Ugric settlement and material culture.
