Humanyun's Tomb is one of the master piece of mughal architecture. Built in the 16-th century by Haji Begum, the persian born first wife of Mughal Emperor Humayun, the tomb is a perfect blend of persian and mughal architechture. It is the first garden tomb built on the Indian subcontinent. Recognized by UNESCO as World Heritage Site in 1993, it has undergone extensive restoration work which completed in 2013.
Humayun's tomb complex encompasses several other monuments besides main tomb. To the right as you enter the complex, Isa Khan’s tomb is a fine example of Lodi-era architecture, constructed in the 16th century. Further south is the monumental Khan-i-Khanan’s tomb, plundered in Mughal times to build Safdarjang’s tomb.
