The 125-year-old Old High Court Building in Nagpur, Maharashtra, and two Mughal-era monuments in Agra — Haveli of Agha Khan and Hathi Khana — are among the six monuments declared protected and of national importance by the Archaeological Survey of India (ASI) in 2018.
The ancient Neemrana Baori in Rajasthan's Alwar district; the Group of Temples at Ranipur Jharail in Odisha's Bolangir district; and the Vishnu Temple in Kotali, Pithoragarh district, Uttarkhand, are the three other monuments that have been listed.
In 2016 and 2017, no new monument was included in the list of sites of national importance. The last monument to be included in the list, in 2015, was the Vishnu Temple in Nadavayal in Kerala's Wayanad district.
The list was presented in the Lok Sabha on December 24, 2018, by the Ministry of Culture in response to a question by the Shiv Sena MP from Ramtek, Krupal Balaji Tumane. Replying to the question, the Ministry said that the ASI takes up a survey for documenting/reporting ancient monuments/sites through exploration, and that a village-to-village survey and conservation of monuments is a continuous process.
