I used to call it a cask church because it was too big and it felt like it was made of wood. It was small, with a few rows of chairs, a small podium, no photos, no talking, probably the name. Located in the downtown area, next to the big shopping mall, there is a very unique shape on the entrance square. I didn't know what the building was, it was very special. Not far from Helsinki Railway Station anyway, the whole city is not big.
