| 4. Ruins of The Castle of Haapaniemi, Kisko |
Kisko has lots of interesting sights, but not all of them just 'exploration' sites. Here we have ruins of a castle from the 16th century that are now taken care of by the National board of Antiquities. The castle was about 13x18 meters wide and belonged to the Haapaniemi manor house totality.
Oh yeah, this place holds our record of the oldest exploration place! :)
