Secretariat Building, New Delhi

The Secretariat Building or Central Secretariat housed the most important offices and ministries of the Government of India, including the Cabinet Secretariat, at Raisina Hill, New Delhi. The Secretariat buildings are two blocks of symmetrical buildings, North Block and South Block, on opposite sides of the great axis of Rajpath, and flanking the Rashtrapati Bhavan (President's House). The buildings were designed by Herbert Baker and form a part of Lutyens' layout for New Delhi. As part of the Central Vista Redevelopment Project, the Government of India commissioned the nearby Seva Teerth (Executive Enclave) and the Kartavya Bhavan (Common Central Secretariat) to modernize and consolidate central government offices with phased moves from the Secretariat Building occurring in 2025–2026. The North Block and South Block buildings are currently being repurposed as the Yuge Yugeen Bharat National Museum.

Seva Teerth is an integrated administrative complex housing the new Prime Minister's Office (PMO), the Cabinet Secretariat, and the National Security Council Secretariat and the Kartavya Bhavan houses key ministries and departments that previously occupied the Secretariat Building and various older ministerial and government buildings across New Delhi.
