Siniallikas (blue spring) was an ancient sacrificial spring, named after its crystal clear water and its characteristic blue colour from the blue clay at the bottom.
According to a legend, a blue-eyed maiden, who was teased by the manor owner, drowned herself in the spring.
The spring is said to reveal a treasure if seven brothers drink from it together. The water of the Siniallikas spring was believed to have the power to heal. Silver coins were thrown into it as a sacrifice.
Nearby, there is a hill fort, where ancient Estonians built a stronghold in the 12th–13th century, and Lake Sinialliku.
