What cause the decline of classical city masterplanning? A Greco-Roman

>>3060248

the transition happened as the system that copy-pastad urban centres like that, and maintained roads and water infrastructure and trade and the army etc..., collapsed

the reversal to organic defensive implosion was a reaction to a doomsday scenario of crisis, invasion, depopulation and infrastructural collapse and sudden scarcity

much of the early middle ages is basicaly what a postapocalipse culture would look like after a generation

As far as I know, the only city that survives well into middle ages with this form is Constantinople

Interesting... a style of city planning created and used by a specific culture disappeared when the said culture and its technological achievements disappeared. What a weird coincidence... Surely uneducated barbarians would've built similar regular cities, with theatres, colosseums...

>are there any city that still build in/retain Roman city function well after antiquity?

Spanish cities in Latin America?

Like bro just IMAGINE how advanced we would be if Rome never got destroyed by the Pope

Isn't it just that the terrain upon which the settlements were founded changed?
Most Roman cities were built on a relatively flat terrain, as it would provide better access to roads and therefore trade routes. Most Medieval cities had to be built on hilltops as the plains became too vulnerable and they needed a high enough spot to monitor the movement of possible enemies.
Of course, you can't have a square city planning on a conical terrain like a hill, it'd make more sense to have a concentrical city planning following the hill's slopes and centered on a castle or a citadel.

I think Barcelona's Eixample is a great tribute to it. It gives a sense of structure to the city while not falling victim to the "rows upon rows" grid formation of NYC.
