Situated to the East of the tomb of Nasiruddin Mahmud (Sultan Ghari), off the Mehrauli Mahipalpur Road, the ruins of these residences date back to the late Mughal period of the 17th – 18th centuries, thus making them the oldest surviving specimens of residential architecture in Delhi.
The Tomb of Ghiyas ud din Balban (1287 AD), situated within what is now known as the Mehrauli Archaeological Park, occupies a position of immense importance in the evolution of architecture in India. It was in this structure, that for the first time, true arches were employed in the spanning of openings. All Islamic buildings built before this tomb contain ‘false’ corbeled arches.
The tomb of Mubarak Shah (died 1434) is situated within Kotla Mubarakpur, at the heart of the modern day New Delhi South Extension I. The structure is one of the early tombs to be modelled on the typical octagonal style that rose to prominence during this period.
The Rajon ki Baoli, inside what is known today as the Mehrauli Archaeological Park, is arguably one of the most beautiful baolis in Delhi. Constructed during the reign of Sikandar Lodi (1489-1517), it derives it’s name from being first used by masons (raj). It consists of four tiers, adorned by elegant arcades, with steps leading down to the water level, which usually remains below the second level from the bottom. As in most other baolis, a well at the back allows for water to be drawn up directly using a bucket. Attached to the west of the baoli is a mosque and a twelve pillared tomb.
Tucked away inside one of the many ‘pockets’ of Purani Dilli (Old Delhi), the Kalan Masjid (1387) is one of the seven mosques built by Khan i Jahan Tilangani, Firoz Shah Tughlaq’s prime minister. Stylistically similar to it’s six contemporaries, it is one of the few medieval mosques of Delhi which are still in use.
