"All cities are mad, but the madness is gallant"

From Gladys We, who lurks on MetaFilter:

Planned cities are not a new idea (Palmanova, Italy, 1593). From Washington, D.C. (1791), to Canberra, Australia (1911), to Brasilia, Brazil (1957), planned cities have long been an urban dream (from space), perhaps most frequently applied to national capitals. But they don’t always work out as planned.
In North America, some argue that everything settled after the 1871 Dominion Lands Act in Canada or the Northwest Ordinance of 1787 in the US counts as “planned” because it was platted before the settlers arrived.
Contrast
Broughton, NS (perhaps Canada’s first planned town; current population 24),
New Haven, CT (the US’s first planned town (1638)),
Savannah, GA,

with

Chicago, IL, the Burnham Plan and Pullman, Chicago;

Detroit, MI;
Williston, ND.
Perhaps consider:
Mexico City, Mexico, which has turned its city planning muscle to green planning
Guadalajara, Mexico, which has an original colonial town plan, a 1950s revamp, and an ongoing reworking
Elsewhere in the world planned cities are often schemes of vainglorious dictators:
Dubai, UAE
Ashgabat, Turkmenistan
Astana, Kazakhstan
Kolmanskop, Namibia (abandoned diamond town)
Planned Al-Noor City to build a bridge over the Red Sea
Or they may be very ancient:
A 4500-year-old planned city in Karachi, India?
Catalhoyuk, Turkey: 9000 years old? 10,000 years old? Really old.
