In this investigation, I’m examining the systems that appear to vanish from the record after the early 1700s. Before this period, cities show signs of coordinated infrastructure—large-scale construction methods, unified planning, and systems that seem to operate beyond individual buildings. Afterward, many of these systems stop appearing altogether.
What replaces them is often smaller, simpler, and more fragmented. Techniques are no longer repeated. Infrastructure is repurposed rather than rebuilt. Records describe progress, yet the physical evidence suggests something different: capabilities that existed earlier are no longer present or understood in the same way.
This isn’t a claim about collapse or intent. It’s an inventory of absence—systems that stop being built, maintained, or even described after a specific point in time.
Something systemic disappears after the 1700 catastrophe. I’m not offering explanations—just documenting what no longer returns.
