The Ministry of External Affairs is largely located in South Block, a building that also houses the Prime Minister's Office and the Ministry of Defence. Offices of Ministry of External Affairs are also housed in Jawahar Lal Nehru Bhavan, Shastri Bhavan, Patiala House and ISIL Building.

South Block, and North Block situated across the road, were built on top of Raisina Hill in 1931. Designed by Herbert Baker, one of Britain's most distinguished architects of the early 20th Century, the two impressive Secretariat buildings flank Rashtrapati Bhavan on each side of the Central Visitor. South Block is an intricate labyrinth of vaulted staircases and high-ceiling passages. Colonnades and flat roofs, dominated by huge domes are striking features of this building.

At home, the Ministry of External Affairs is responsible for all aspects of external relations. Territorial divisions deal with bilateral political and economic work while functional divisions look after policy planning, multilateral organizations, regional groupings, legal matters, disarmament, protocol, consular, Indian Diaspora, press and publicity, administration and other aspects.
