In Estonia, springs have always been considered holy; most were thought to have healing powers.
Blue Springs of Saula include three quite large springs with a water flow of 20–30 m per second. The variation in colour of the springs (Siniallikas is greenish blue, Mustallikas is brownish black and Valgeallikas is greyish blue) is caused by light reflecting on sand particles, floating on the bottom of the springs, through the clear waters.
Old folk say that the water of the springs heals all ailments if you sacrifice silver jewellery, money or beads.
If you do not offer a sacrifice, a Harju County sprite called Blue Springs Tölp might just come and get you!
