Sacred stone, spring or grove
Toomemägi sacrificial stone

On the north side of the cathedral ruins on Toome Hill in Tartu lies a large boulder that is counted among Estonia's roughly 400 sacrificial stones, places where people once left gifts, usually bloodless ones, for their old gods. The stone has found a new ritual in a university town: at the end of the academic year students gather here to burn their lecture notes after the last exams. Just behind it rises the little Kissing Hill, up which newly married grooms are expected to carry their brides.

Eesti keeles
Tartus Toomemäel, toomkiriku varemetest põhja pool, lebab suur kivi, mida loetakse Eesti umbes 400 ohvrikivi hulka – paikadeks, kuhu inimesed viisid vanadele jumalatele ande, enamasti veretuid. Ülikoolilinnas on kivi saanud uue kombe: õppeaasta lõpus kogunevad tudengid pärast viimaseid eksameid siia oma loengukonspekte põletama. Kohe kivi taga kõrgub väike Musumägi, mille otsa noored peigmehed peavad oma pruudi üles kandma.
