general Mahabat Khan in 1625–26, during the reign of Jahangir. This structure is known for its unique architecture, as it is octagonal on the outside while square within; its ceiling is decorated with painted and incised plaster, it has a high neck dome and shows a conspicuous absence of a double dome feature, common to tombs of the period. Chillah Nizamuddin Aulia: Believed to be the residence of patron saint of Delhi, Nizamuddin Auliya (d. 1325), is located just outside the main complex, near the northeastern corner of the principal mausoleum and is an example of Tughlaq period architecture. Yet further away from the tomb complex, lie Mughal-period monuments, Bada Bateshewala Mahal, the tomb of Muzaffar Husain Mirza, the grand nephew of Humayun, built 1603–04 on platform with five arches on each side, has its interior walls decorated with incised and painted plaster; the Chote Bateshewala Mahal once an arcaded octagonal building with a domed ceiling and stone jaalis. Both these monument now lie inside a commercial area facing the complex's parking lot. Another period structure is Barapula, a bridge with 12 piers and 11 arched openings, built in 1621 by Mihr Banu Agha, the chief eunuch of Jahangir's court. Barber's Tomb: Towards the south-east corner, within the Char Bagh, lies a tomb known as Nai-ka-Gumbad, or Barber's Tomb, belonging to royal barber, it is datable to 1590-91 CE, through an inscription found inside. Its proximity to the main tomb and the fact that it is the only other structure within the main tomb complex suggests its importance, however, there are no inscriptions suggesting as to who is interred therein, the name Barbers tomb is the local name of the structure, hence still in use. The tomb stands on a raised platform, reached by seven steps from the south, it has a square plan and consists of a single compartment covered with a double-dome. Inside lie two graves each inscribed with verses from the Quran. Also, one of the graves is inscribed with figure 999 which may stand for the Hijra year 1590–91. However, in an 1820 watercolour now at British Library, the Persian caption beneath the structure reads, Maqbarah-i-Kokah i.e. "Tomb of Kaka", and Kokah or Kaka in Persian stand for foster-brother (mirak brother), Mirak (a Persian title as sir) though the identity of the person remains unknown, and it might be (incorrectly) referring to another nearby monument in
