Nunnavuori, Stone grave hill in Kakskerta, Turku, Finland.
Nunnavuori is a registered archaeological hill in Turku reaching about 63 meters in height, featuring a nature reserve with a boulder field on its summit. The site sits between Runosmäki and Impivaara and shows layers of glacial geology and stone formations across its slopes.
During the Ice Age, glaciers covered the entire hill, and as they melted, the area transformed into a beach environment with smooth rocks. These processes created the geological structures visible today and shaped the landscape we see now.
The name Nunnavuori comes from regional dialect meaning giant, reflecting old stories about supernatural beings who placed massive stones across the landscape. These tales continue to shape how people experience the boulders scattered on the hillside today.
The site is reachable by bus line 18, with the nearest stop at Signalistinkaari from where it is a short walk to the site. The surrounding hiking trails are clearly marked and let you explore the various parts of the nature reserve at your own pace.
The site contains a geological formation called pirunpelto, a boulder field that records the different historical stages of the Baltic Sea. This rare formation offers an unusual view into how the landscape has changed over thousands of years.
