Humayun's Tomb: The Monument That Made the Taj Mahal Possible

If you visit the Taj Mahal without first seeing Humayun's Tomb, you are seeing the masterpiece without understanding its origins. Built in 1570 AD — exactly 72 years before the Taj Mahal's completion — Humayun's Tomb is not merely a beautiful monument. It is the architectural prototype from which the Taj Mahal was directly and consciously derived.
Every major design principle that defines the Taj Mahal was first tested here: the double dome (an outer dome for visual grandeur, an inner dome for correct interior proportions), the charbagh (a four-part formal garden divided by water channels, drawn from Persian cosmology), the iwans (massive vaulted archways on each face of the tomb), the use of white marble contrasted against red sandstone, and the placement of the tomb at the geometric centre of a vast formal garden.
The Mughal architect who designed the Taj Mahal — and Shah Jahan's own architectural vision — were directly informed by Humayun's Tomb. Without this building, there is no Taj Mahal as we know it.
For these reasons, UNESCO inscribed Humayun's Tomb as a World Heritage Site in 1993, and it is widely considered one of the most important buildings in South Asian architectural history. Yet it remains significantly less crowded than the Taj Mahal, less commercialised than the Red Fort, and is, in the opinion of many architects and historians, the most aesthetically satisfying Mughal monument in Delhi.
