The government will on Friday fully vacate British-era North and South Blocks, which have housed its offices for nearly a century, with the Prime Minister’s Office the last of all segments to move out.On Friday, the PMO will shift to a new address, Seva Teerth, also located in Lutyens’ Delhi but one reflective of Indian architectural elements rather than colonial. Seva Teerth will be home to the Prime Minister’s Office, the National Security Council Secretariat, the Cabinet Secretariat and other crucial segments so far scattered across the city.Sources said the PM would chair the last Cabinet meeting at South Block on Friday, before he vacates the office. After the Cabinet meeting, Modi will inaugurate Seva Teerth and other sections of Kartavya Bhavan — a series of modern government office complexes on the Janpath road close to India Gate.Kartavya Bhavan has 10 complexes which will house all government ministries and departments. Seva Teerth will be a separate stand-alone compound for the PMO and Cabinet Secretariat offices.The two new Karvatya Bhavan offices to be inaugurated tomorrow will house the ministries of Finance, Defence, Health, Corporate Affairs, Education, Culture, Law, Information & Broadcasting, Agriculture, Chemicals & Fertilisers and Tribal Affairs.Importantly, the Home Ministry was the first ministry to vacate North Block in August last year. This was after 98 years of occupation of the Secretariat complex on Raisina Hills.Government departments under British rule had completed their transfer from temporary pre-war quarters in Delhi’s Civil Lines to the Secretariat buildings — North and South Block — designed by Herbert Baker on Raisina Hills in 1926-27.The century-on shift to indigenously designed modern offices is part of PM Modi’s project to decolonise heritage and spaces.Top officials point to the motivations behind the imposing Secretariat buildings which Baker built.These motivations are eloquently recorded in “Indian Summer: Lutyens, Baker and Imperial India”, which says, “The dominating hilltop position of the two Secretariat buildings, removed from ordinary traffic, was meant to impress Indians and indeed to inspire a sense of reverence in all who approached.”Once vacated tomorrow, the Secretariat complex will be handed over to the Ministry of Culture, which is leading the project to build “Yuge Yugeen Bharat”, claimed to be the world’s largest museum.Also, Friday onwards, President Droupadi Murmu will be the sole constitutional authority to reside on the majestic Raisina Hills.First gallery of museum by 2027-end: ShekhawatUnion Culture Minister  Gajendra Shekhawat told The Tribune, “Yuge Yugeen Bharat Museum on Raisina Hills will be the world’s largest. Restoration work at North Block is underway and at South Block, it will commence soon. The first gallery on Indian civilisation will open by the end of 2027. The museum as a whole will showcase 10,000 years of India’s civilizational continuity.”
