While planned-out Paris gets lots of love, London, with its architectural diversity, is a better model for us.

Monumental structures (like Big Ben) need some green space to breathe (thank you, the Commons at U.S. Bank Stadium). Too much space, can make a place feel oppressively empty.

Block E should have become a public area, like Piccadilly Circus.

The Art Institute should have been closer to downtown, perhaps by Loring Park.

The Cathedral of St. Paul should have included an open area for people to gather, like Sacre-Coeur.
