This structure isn’t really floating–as far as I know–but it looks like it is. It’s in New Delhi off the Rajpath between the President’s abode and the India Gate.
The India Gate honors 70,000 Indians who died during World War I fighting on behalf of the United Kingdom. Beneath the arch is India’s Tomb of the Unknown Soldier.
It’s India’s answer to the Arc de Triomphe, and it sits at the opposite end of the Rajpath from the President’s house, i.e. the Rashtrapati Bhavan. Like the President’s house, the Gate was designed by Edwin Lutyens, a famous British architect.
The India Gate is among the must-see sights for visitors to New Delhi.
