After the shock of the Tour_Montparnasse in Paris in the early 1970s, almost all new tall buildings for the_Paris_region would be constructed in La_Defense.
Before central London or the inner City_of_London finally allowed much taller buildings, the Isle_of_Dogs was selected as an alternate high-rise core. Especially, the Canary_Wharf complex.

Perhaps someday W,DC will have its own equivalent of La_Defense.
