Near the Molėtai Observatory, on the picturesque bank of the lake Lenktinis, there are the remains of the buildings of an old ethnographic homestead - a cellar, a barn, and a bathhouse. This homestead, at the entire southern strand of the lake Lenktinis, belongs to the Molėtai Land Museum. In 1996, an ancient observatory of celestial bodies - a sacred place - was set out near the homestead. In the middle of the circle of ten wooden poles with calendar signs of the shrine, a stone Sun-fire altar was mounted. The poles mark six countries of the world and the azimuths of rising and setting of the Sun on the days of the most important calendar festivals. While visiting this place you can get the impression the way celestial bodies were observed in ancient times and the way people did calendar calculations.
