Humayun's Tomb, Delhi
Concierge.com's insider take:
Akbar, Humayun's son and the greatest of India's Mughal emperors, built this awe-inspiring monument, probably between 1562 and 1571. His intention, righteously achieved, was to honor his father, India's second Mughal ruler, who had fallen down a flight of stairs to his death. Less flamboyant than the Taj Mahal (which it helped to inspire), Humayun's tomb, composed of earthy red sandstone and pure white marble, is nonetheless quietly impressive. The tomb is surrounded by a meticulously kept garden, divided into precise squares. The garden recently underwent extensive renovation, and water now flows through its hand-chiseled stone channels and fountains (previously dry for four centuries).
