Humayun's tomb (Persian: آرامگاه همایون‎ Maqbara e Humayun) is the tomb of the Mughal Emperor Humayun in Delhi, India. The tomb was commissioned by Humayun's first wife Bega Begum (Haji Begum) in 1569-70, and designed by Mirak Mirza Ghiyas, a Persian architect chosen by Bega Begum. It was the first garden-tomb on the Indian subcontinent, and is located in Nizamuddin East, Delhi, India, close to the Dina-panah citadel also known as Purana Qila (Old Fort), that Humayun founded in 1533. It was also the first structure to use red sandstone at such a scale. The tomb was declared a UNESCO World Heritage Site in 1993, and since then has undergone extensive restoration work, which is complete.
