Ramesh, who visited the incident spot in the morning, said two offers of land -- one between Pragati Maidan and Delhi Zoo and the other near Botanical Garden in Noida -- did not work out.
"I had even arranged a six-acre land for the museum between Pragati Maidan and Delhi Zoo, so that the museum could be relocated. This (the present location) is not the right location for the museum. For some reason, the relocation could not take place.
He said even the Parliament building, and government buildings like Shastri Bhawan and Udyog Bhawan are vulnerable to incidents of fire.
The museum, established in 1978, comes under the Union Environment Ministry.
