I am not really sure if the things I mentioned would count a 100%, but anyways I think they are interesting enough to be mentioned.
- IIT Kharagpur/ Hijli detention camp
The large numbers of those who participated in armed struggles or the non-cooperation movement against the British could not be accommodated in ordinary jails. The British colonial government decided to establish a few detention camps; the first one was located in Buxa Fort followed by the creation of Hijli Detention Camp in 1930. A significant moment in the Indian independence movement occurred at here in 1931 when two unarmed detainees, Santosh Kumar Mitra and Tarakeswar Sengupta, were shot dead by the Indian Imperial Police. Subhas Chandra Bose came to Hijli to collect their bodies for interment. Many Indian nationalists, including Nobel laureate Rabindranath Tagore, voiced strong protests against the British Raj over this incident. The firing which later known as "Hijli firing" is the only incident of police firing inside a detention camp.
I provide a quote by Nehru
Here in the place of that Hijli Detention Camp stands the fine monument of India, representing India's urges, India's future in the making. This picture seems to me symbolical of the changes that are coming to India. src
One more thing worth mentioning is this is the place where the to be CEO of google himself would study metallurgy.
- Fort William
Fort William is a fort in Hastings, Calcutta (Kolkata). It was built during the early years of the Bengal Presidency of British India. It sits on the eastern banks of the Hooghly River, the major distributary of the River Ganges. One of Kolkata's most enduring Raj-era edifices, it extends over an area of 70.9 hectares.
The fort was named after King William III. In front of the Fort is the Maidan, the largest park in the country. An internal guard room became the Black Hole of Calcutta. Today it is the Headquarters of Eastern Command of the Indian Army.
- Indian Penal code
These are only a few examples, but I think it is impossible to separate Indian history with British history. You can white wash what something looks like from outside, but that won't cause any meaningful change in practice.
