There's a short list of things to see in Helsinki, most of which don't cost very much, are free of charge, or have free days. Specifically, there were four architecturally significant places of worship I wanted to see. This was one of the two I actually went into, and the one I liked the most. The other was the Russian Orthodox (Uspenski) Cathedral, not far from the main cathedral, Helsinki Cathedral, which is placed atop a very long flight of steps such that it seemingly presides over the harbor.
It is Temppeliaukion kirkko, also known as the "Rock Church" for simplicity's sake. In a way, I found this slightly humorous because words like harvest, bounty, friendship, journey, and, yes, even rock are found quite often across America as names for nondenominational evangelical MAGA-megachurches. Rest assured that, here, the "Rock Church" is about this unique church being chiseled and built into a large preexisting outcropping of granite.
Because it is low slung and the entrance is small and recessed, it looks like it might be a small church. It is larger than it may seem once inside, but could be considered a medium-sized church.
Inside, Temppeliaukion kirkko is impressive and has a good feel about it. Its denomination is Lutheran, as might be expected in Finland, but its interior is largely devoid of specific religious references. Its roof is a bowl-like shaped copper dome, into which angled windows are placed beneath it and hold up the dome via the window framing around the circumference. This makes for plenty of light inside, regardless of the weather outside. The walls below the windows are of exposed rock. To one side is an impressive pipe organ. The organ, the pews, and other areas also feature exacting woodwork. It's a tough church to pin down in terms of when it was built, initially thinking it would have been the '70s or '80s. It was opened in 1969. Most of the seating is on the main floor, and it is padded, with some seating on an upper level that resembles a theater balcony. Both levels' seating is angled, making for even more dynamic views of the interior, none of which are quite the same. Be sure to see, and sit on, both levels.
If expecting to be vowed with "flash" factor, this isn't going to work for you. If you want to soak in craftsmanship, silence, and a reflective atmosphere, it will work for you. Its understated affect makes it 180 degrees from anything that is "holy roller" in nature. Thank God for that.
The entrance fee was 5 Euro. The ticketing and information area are interestingly placed under the balcony and close to the entrance.
To round out discussing the city's major churches that would appeal to tourists, Uspenski Russian Orthodox Cathedral is free of charge. If you can manage the flight of steps, or want to, I'm sure that the big white Helsinki Cathedral on its hill is impressive. (Many exterior surfaces were icy that day.) Lastly, the very unique - maybe even quirky - and newer Chapel of Silence in the Kamppi district was closed while I was there.
The convenient and clean Metro does not travel that close to the "Rock Church." You can walk the rest of the way. If you want to get closer to it on transit, one of the excellent tram lines that interface with the Metro will work.
