Delhi, a city dotted with historical monuments and said to have been continuously inhabited since the 6th century, already fulfils two of the basic criteria for Unesco's World Heritage City status, says a leading conservation expert.

"Unesco requires that a city should be of significance to human civilisation to get World Heritage City status and Delhi fulfils it," said A.G.K. Menon, convenor of the Delhi chapter of the Indian National Trust for Art and Cultural Heritage (Intach).
