Jarmo and I visited the Ingels bunker. Unfortunately, it turned out that we could only find a concrete slab, and found no way to enter or peek inside, or even figure out if there was anything underneath.
At first it seemed like the concrete slab had a possible opening underneath, but it didn't lead further than 10-15 cm under the slab.
The bunker is next to the road, as seen below (coordinates: N 60.15290732 E 24.40634994):
We looked for openings, but they had been either filled or simply did not exist any more. This odd structure was nearby though, at the beginning of a ditch... couldn't see a pipe though, although it could of course have been somewhere deeper. Ditch/pipe structure, or part of bunker? Unknown.
