The most impressive public building may be the one nobody was supposed to see.
A brick-built main canal ran beneath North Street. kar-NOON-toom's water and drainage systems developed through several phases. Urban infrastructure included wells, wooden pipes, brick conduits and later replacement routes as systems aged or clogged.
Treat the street surface as the roof of an engineered system carrying water and waste.
The evidence level here is excavated urban drainage infrastructure.
Keep the early fourth century in mind: the reconstructed quarter presents a late phase of a city that had already been growing and rebuilding for centuries.
The frontier metropolis worked because thousands of ordinary routines supported the famous events that survive in textbooks.
For someone already familiar with kar-NOON-toom, the useful detail is scale: the object in front of you belonged to a network much larger than the surviving ruin.
Do not let the modern quietness mislead you. The ancient setting depended on traffic, labor, maintenance, noise and repeated social routines.
One of kar-NOON-toom's strengths is that archaeology can test the attractive story against material evidence—and sometimes force us to tell a better, less convenient story.
