Helsinki's recreation islands are interesting, also from the point of view abandoned military structures and ruins. Today's excursion was to Sirpalesaari.
In Sirpalesaari there are ruins of an early 1900th oil tank, a huge round structure. And the ruins of several gun positions, including a storage (?) rooms under the cliff that they are on.

On and off-piste skiing on all continents, skiing into craters of live volcanoes, climbing, photography, and travel." The Planetskier blog focuses on skiing, caving, climbing, biking, flying, sauna, and swimming adventures around the world.
