Humayun's Tomb was built in 1565 A.D., posthumously, in the memory of Humayun by his widow Hemida Banu Begum. Also known as Tomb of the Perfect Man or 'Insan-i-Kamil', which now stands as a UNESCO Heritage site, was once used as a refugee camp for the war affected populace and travelers during the British rule.
The main gateway of Humayun's tomb ushers a person in front of a large square enclosure which is the tomb of the Humayun situated at the center standing on a beautiful marble pedestal. One of the most notable creations that one can witness in the premises of Humayun's Tomb is Arab Serai. Arab Serai was designed especially to accommodate more than 200 Arabs who were brought by Hemida Banu Begum herself from Mecca as refugees.
A prominent feature of any Mughal design is the perfect harmony between the bliss of the nature and man-made contours. Humayun's Tomb is no exception when it comes to the tryst between nature and man. Within the walls of this monument, garden squares (chaharbagh) surround the entire structure. Paved with pathways for water channels and exquisite flora sprawling around the lush green area, the garden serves as an ideal place for people looking for serenity in the confinements of the otherwise "always on the toe" city of Delhi.
