Architect: Louis Kahn
If Louis Kahn's Hurva Synagogue was actually built, it might have been his greatest building. The general form of the building takes inspiration from the ziggurat, while the congregation would have been organized under tall, trapezoidal, supports that supported the roof of the building. Louis Kahn thought of these massive columns as trees. The faithful would be learning about the Jewish faith under the trees, which harkened back to Kahn's notion of school originating as a group of people learning, together, beneath the shade of a tree.
