The tomb of the Mughal Emperor Humayun in Delhi, India.
Humayun was the second emperor of the magnificent Mughal Empire that ruled most of what is now India, Pakistan, Afghanistan, and Bangladesh for nearly 350 years (from 1526–1858).
He spent most of his life trying to stabilize and hold onto the Empire his father, Babur, had established. He was ultimately successful, with assistance from the Persian Shah, in removing all rivals and thus paving the way for Mughal rule in northern India for the next three centuries.
Humayun loved astrology and astronomy, and built observatories that lasted centuries. He was an avid student of knowledge and established a great library in his palace. It was here in this library where he was descending a flight of stairs, with his arms full of books, that he tripped and fell down, dying 3 days later. He was buried in this tomb commissioned by his wife Hamida Banu Begum.
