The Stone Mokas amazes visitors by its sheer size. A smaller stone Mokiukas lies next to it. These stones are in the vicinity of Tauragnai, near Šeimatis village. Legend says that there was a Mokai family. After his wife drowned in a lake, Mokas and his son turned into stones. Geologists say that a glacier brought these stones from Scandinavia to Lithuania approximately 50000 years ago. Stones Mokas and Mokiukas are the only geological natural monument in the Aukštaitija National Park, along with the state-protected mythological object of culture.
