Although Estonia a country is in Europe and only a trip of two hours by plane from Brussels to Tallin, I know so little about it....
Found a great story about the Panga Cliff:
Folk tradition ties Panga cliff as a place of worship and sacrifice for the ancient Saarlanders. It is known that until well into the 19th century, local fishermen poured libations of beer and whisky over the edge of the cliff, especially at midsummer eve, to ensure lots of fish during the coming year. There is a fishing spell that was chanted in Mustjala parish, and it says: "Come, come closer codfish to me. Bite my hook my dearest gray one. My hooks are silver, dipped in gold and slipped in lead."
It is not known whether the requisite virgin was ever sacrificed here, but it is known that the last animal sacrifice took place during the 1960's. Mustjala kolhoz had finally acquired a prize seed bull. The animal was let loose among the cows that were pastured on the cliff meadows. In a delerium of utter happiness and apparently following some ancient instincts, the bull soon made a beeline for the edge of the cliff and over it went. No doubt the fishing was good that summer.
