Neither the Bihar government nor the Centre is doing enough to preserve the glory of the ancient Nalanda University, the ruins of which were recognised as a Unesco World Heritage Site earlier this year, said an award winning archaeologist who, apart from his many finds, once took the Obamas on a tour of Humayun's Tomb.
Karingamannu Kuzhiyil Muhammed, retired regional director (north) of the Archaeological Survey of India (ASI), said it wasn't enough for a site to get Unesco heritage status.
