Lentokenttä glacial erratics

Lentokenttä glacial erratics are numerous large boulders scattered across the landscape near Turku Airport, showing different mineral compositions and geological structures. The site features clear pathways and informational signs that help visitors understand the rock formations.

These boulders were transported and deposited by massive ice sheets during the last Ice Age around 12,000 years ago, shaping the Finnish landscape. They came from locations hundreds of kilometers away, carried by ancient glacier movements.

The largest boulder is called Devil's Den by local people, reflecting older beliefs that connected unusual rock formations with supernatural forces. Such names show how the landscape has captured people's imagination for a long time.

The site has good pathways and accessibility for visitors who want to see the rock formations up close. The best time to visit is during warm and dry weather when paths are easiest to walk.

The mineral makeup of the stones carries clues about where they came from, pointing to distant locations in Scandinavia. This makes the site a natural record of how glaciers moved during the ice age.
