From Wikipedia, the free encyclopedia

Nunnavuori is a 63-meter tall hill in Finland it is located between the Runosmäki residential area and the Impivaara Sports Center. From the top of the hill, the southern and southeastern parts of Turku are visible.[1]
During the ice age all of Nunnavuori was covered by ice, after the ice started to melt, Nunnavuori became a beach which caused rocks to form a shingle beach, which is today called "pirunpelto". The rocks are most often round and smooth, which was caused by the sea after the ice age.[2][1][3][4]
