A historic sauna is worth the trip on its own — for the building, the tradition, or both. Some of these have been running continuously for a century, others are careful restorations of bath culture that nearly didn't make it. Either way, the session carries a weight you don't get from a new-build, and the löyly tends to be taken seriously.
In Helsinki, 2 of the curated saunas fit this cut. See the full Helsinki guide for every venue in the city, or keep scrolling for just the historic saunas.
