I can't think of a more important one. I am reminded of the song in the Cole Porter musical in which they are singing about women. And that is true of Chandigarh. Those of us who now have had the privilege to see it for the first time understand why. It is truly marvelous.
Legacy is both prospective and retrospective.
After all, Chandigarh was a new creation, but nothing is totally new under the sun. There are numerous analogies between the two. There was a pre-existing village there called Georgetown, which has been allowed to remain. Washington has a beautiful river and a plan, which has been defended and ignored at various times. Washington had a great influence - Canberra was modeled after it.
