Metcalfe House, also known as Dilkusha, is a ruined Mughal tomb later adapted as a country retreat by Sir Thomas Metcalfe. It began as the tomb of Quli Khan, connected to the court of Akbar, before being remodelled in the 19th century.
The site is close to Qutub Minar and Mehrauli Archaeological Park, so it works best as part of a wider walk through Mehrauli's tombs, stepwells, and ruined garden buildings.
