Consider the two images attached - a Byzantine and Gothic cathedral. Both are beautiful and good, but changes in building materials and techniques yielded the second from the first. There's also a continuity between the two - similar liturgy, similar function, similar form.
Most construction today is no longer of stone, but of metal and glass. One WTC is a very beautiful building. Is it possible to reverently approach church architecture with the materials and techniques of One WTC, or does it necessarily evolve into modernist designs that lose continuity? If we had a reverent metal and glass cathedral, what would it look like?
