The mausoleum complex of Humayun, India’s second Mughal Emperor, was commissioned by his widow in 1565 and was the first garden tomb to be built in India, taking seven years to complete. Humayun had travelled widely in Persia and Central Asia during his lifetime, and many of the architectural principles he brought back from these journeys were incorporated into the building at his wife’s instructions. With its double domes, decorative inlaid marble and vast garden with pools connected by channels, this 16th Century building set the stage for the style that culminated in the Taj Mahal almost 100 years later.
