This front wall of this church was built adjacent to a slab of granite. Other rocks were added to the walls so the structure resembles a cave or grotto. The domed roof provides excellent acoustics. The church has a modern entrance with a reception desk and gift counter. Other than the architecture, there is little ornament in the church which beckons. I say that because there is a 5 Euro charge to get into the church up close. If you want to save your money, you can see the whole thing very well from the reception area. I would not say it is a "must see." We did pay the fee however, as we happened to visit on a Friday afternoon when they have a concert of experimental music. I still need to recheck the dictionary definition of "music" because I suspect this performance missed the mark. The performers may have been very talented but the caterwauling was the worst thing I have heard. By the way, the church offers no public restrooms.

I love visiting unique attractions and this giant circular "rock church" as it was referenced to me was simply stunning in its simplicity and beauty. Not large so easy to see it all on a short visit, and suitable for children. My daughter seemed fascinated. You feel like you're outside and inside at the same time, in nature and in a manmade structure at the same time. Beautiful to see the sunlight streaming through. Feels like you are outside and inside at the same time, part of nature and inside a manmade structure at the same time

I was overwhelmed by the impression live music made on the athmosphere of the building having never heard it before. This was an extempore visit to a free concert given by the official representative orchestra of Finland, the oldest professional too dating back to 1819. The Guards Band didn't play any classical military music but modern pieces by Finnish composers like Magnus Lindberg's Gran Duo. Sounds by the wind instruments resonated from the rock walls and copper cupola.
