There is a nice website of the Delhi nomination with maps of the two nominated areas:
A nice Web site certainly - but the Nomination??
I note that the original T List description covered 4 of Delhi's historic cities
d. New Delihi
An incredibly complex set of sites - even if a single coherent OUV case could have been made out to cover them all.
Of these a and b have bitten the dust in the Nominated areas as per this Web site. But even a single nomination covering BOTH Shahjahanbad (i.e "Old Delhi") and Lutyens' "New Delhi" seems unmanageable in the context of 21st C India.
I presume they would be linked using the sort of argument which Mexico used to use when linking together a pre-Columbian and a colonial site in the same nomination - continuity and fusion etc.
But for those who know Chandni Chowk etc - what are the chances that India can demonstrate authenticity, integrity, protection, preservation and management across this chaotic area? The map also surprisingly seems to show the Kashmir Gate as being outside the boundary - although it is highlighted as a "Heritage Building". And the early 20C railway station is included! A large part of the site of course is already inscribed in the form of the Delhi Fort.
Could India not bring itself to nominate only the colonial Lutyens planned city? That would have been a big ask but would appear to be more manageable
