The next best architecture would be THE VICTORIA MEMORIAL of KOLKATA.
Despite of their remorseless rule, I must say that the British Colonial Era also gave India some of the most amazing architectural gems. Built to highlight the glory of British Empire in India, this monument amalgamates the best of Mughal and British architectures. This imposing monument was inaugurated in 1921 paying tribute to Queen Victoria. At present, this monument has a remarkable assemblage of maps, paintings, weapons, coins, sculptures, artifacts, stamps, etc.
