The Lal Bahadur Shastri Memorial remembers India's second prime minister, who led the country after Jawaharlal Nehru and died in office in 1966. The museum is small and biographical, with photographs, personal objects, and the political atmosphere of early post-independence Delhi.
It is a worthwhile add-on if you are already tracing modern Indian history around Lutyens' Delhi, especially after Gandhi Smriti or the National Museum.
