Humayun's Tomb historical timeline

Humayun’s Tomb turned an established sacred burial area near Nizamuddin Auliya into the Mughal dynasty’s first monumental garden-mausoleum. Its later history is unusually legible because the complex retained its funerary purpose while gardens, waterworks and surface materials were repeatedly altered and restored.

Chronology

1. 1325 Nizamuddin Auliya dies and is buried nearby. The shrine makes the surrounding district desirable for later burials, a relationship still clear across the Nizamuddin ensemble.
2. 1547 Isa Khan’s octagonal garden-tomb is completed before Humayun’s mausoleum. Its lower enclosure now forms the visitor’s first major architectural sequence.
3. 1556 Humayun dies in Delhi. His burial creates the need for a dynastic mausoleum at a site close to the revered Sufi shrine.
4. 1560s Persian and Indian craftspeople construct the garden-tomb under Mughal patronage. The high platform, irregular octagon and four-part garden establish the plan that survives.
5. 1570 The mausoleum is complete. Its double dome and monumental scale become a reference for later Mughal funerary architecture.
6. 1857 The last Mughal emperor, Bahadur Shah Zafar, takes refuge here before British capture. The complex becomes part of the physical record of the dynasty’s end.
7. 1993 UNESCO inscribes Humayun’s Tomb under criteria (ii) and (iv). The protected property includes the wider group of tombs, gateways and gardens, not only the central building.
8. 1997 A long ASI–Aga Khan conservation partnership begins. Garden channels flow again after the 1997–2003 phase, while later work removes damaging modern materials from the tomb.
9. 2016 UNESCO approves a minor boundary modification. The enlarged property better recognises the connected funerary and garden landscape around the main enclosure.

Survival and restoration

The central mausoleum, gateways and subsidiary tombs retain their main form, purpose and setting. Twentieth-century concrete and cement repairs, however, changed how parts of the building shed water and concealed original stone or lime work.

Recent conservation used archaeological research and traditional materials to reverse some of those interventions. Lime concrete replaced roof concrete, lime mortar replaced cement plaster, and original paving was exposed and reset. Restored water flow returned movement and sound to the garden without pretending that every planting survives unchanged.
