In the bed of the Neris, closer to the left bank, lies a stone called Balnu. It is mentioned as early as 1857. Anxious in the book of the swimmer Konstantinas Tiškevičius "The Neris and its banks". The stone is indeed reminiscent of a saddle and was thus named most likely by pastors.
In this place the Neris flows compressed between the high banks and makes a turn, so the rapid current of the river, at the entrances of the Purvė ravine, brought souls to the treacherous stone. While pushing the souls further, one had to sit on the Saddle and work.
