Situated in the heart of New Delhi, India Gate was designed by Sir Edwin Lutyens and unveiled in 1931. Originally known as All India War Memorial, it commemorates the soldiers of Indian Army who lost their lives while fighting as British allies in the First World War and the Third Anglo-Afghan War.
13,300 Commonwealth servicemen are commemorated by name. The Delhi Memorial also acts as a national memorial to all the 70,000 soldiers of Undivided India who served and died in every main theatre of operations except Italy during the First World War, the majority of whom are commemorated by name outside the confines of India.
Burning in a shrine under the arch of India Gate since 1971 is the Amar Jawan Jyoti (the flame of the immortal soldier) which marks the Tomb of the Unknown Soldier.
