One of the great works of architecture of Old Delhi, India, is the monumental tomb of the Moghul Emperor Humayan (d. 1556). He was the son of the founder of the Moghul Dynasty, Babur, but internal divisions led to Humayan being exiled in Persia for a fifteen-year period from 1540 to 1555. Whilst in Persia, he saw the magnificent architecture of the Persians, both tombs and mosques, and thus inspired Humayan built the first really grand funerary edifice in India, a sort of granddaddy to the Taj Mahal. The tomb is still surrounded by its walls and large garden, a place of tranquillity amidst the chaos of Delhi, a city of 16 million people. Elevated high on a platform, the domed structure dominates the garden like a massive mountain of red sandstone and white marble.
