Nai ki Kot--The Fortresses of Adilabad
South of Tughlaqabad and once connected to it by a causeay is the fortress of Adilabad, which was built by Muhammad-bin-Tughlaq. In plan it is a smaller version of Tughlaqabad, with the trademark sloping walls of huge stone. Inside Adilabad was the legendary Qasr-i-hazaar satun or the Palace of a thousand pillars, which seems to have been a really popular idea back then (see Bijai Mandal). The palace had a huge audience hall, which was built on columns of varnished wood. Towards the southern gateway you can still see a vaulted corridor which used to be flanked by guardrooms. Adilabad has all the marks of a fine Tughlaq building with that style's typically austere walls, bare surfaces, corbeled arches and crenellation.
Outside the fortress towards the east is the Barber's fort. It is not known whether a barber actually ever lived in the tiny fortress of Nai ka kot (barber's fort), but it seems Ghiyas-ud-din certianly did. He used this place as a temporary residence when Tughlaqabad was coming up. It is built in the same style as Adilabad.
