Peter Zumthor, the lemniscate, Part 2. While one finds many free-standing architectural masterpieces that utilize a single geometrical shape, few buildings have had an impact on me more than Peter Zumthor’s (1943-) Caplutta Sogn Benedetg near Sumvtig, Switzerland (1985-1988). The chapel, its siting and usage of materials, and the all-encompassing interior space are pure poetry.
