The island of Saaremaa used to have a number of old windmills, but due to industrialization a lot of them have become obsolete and now lie in ruins. Two of the windmills were remade by a local seaman Aleksander Tarvis with help of neighbourhood community as a remembrance to local mythological giant Suur Tõll and his wife Piret.

The windmills were initially rebuilt for a documentary in the end of 1970s but since then have became popular among tourists. Also newlyweds started a tradition to bring stones with their names and marriage date for good luck and place them under the windmills. There is no proof if a special blessing has become out of it but the windmills are still loved and a visited site.
