Our family used to attend Newman Hall Church in Berkeley, California back in the '90s -- a very brutalist building of a church. Although religion never took for me, I had fond memories of the after-church donut feasts in the community space.
I don't know if the intention of the architecture was to get me to focus on the mass, but young me just spent the entire time taking in the strange geometries of the place.
