Built in 1565, Humayun’s tomb lies in the middle of a huge Mughal garden (chahar bagh) enclosed by walls, resembling a blissful abode in the paradise of Allah. The monument is immediately striking for its perfect proportions and the stark contrast between the red sandstone and the white marble, as well as for the extraordinary transformation in architecture achieved since the construction of Isa Khan’s tomb a mere two decades earlier. Don’t miss the tomb chamber, which is a masterpiece of simplicity and balance.
