I once watched a documentary on Pompei...it was laid out in lots and blocks very similar to modern cities. I thought that was amazing.
The irony was Rome was about as unplanned a city as they come. But when the Romans started a city from scratch they used urban planning.
I was watching a documentary this weekend, that showed wear patterns on the ancient roads. It showed that Pompeii had distinct one way streets in the marketplace.
The more things change, the more they stay the same. :-)
It was probably the same documentary. lol
