Humayun's tomb in Delhi was commissioned by his wife Bega Begum as the first Mughal garden tomb in India. It was designed by Persian architect Mirak Mirza Ghiyas and represents a fusion of Persian and Indian architectural styles. The complex tomb sits within a charbagh garden divided into quarters, and its double dome structure inspired many later Mughal mausoleums like the Taj Mahal. The tomb houses over 100 graves and its symmetrical exterior belies a complex interior layout of 124 chambers radiating from the central chamber housing Humayun's cenotaph.
