Burj Mandal or Bijai Mandal or Jahanuma is the highest point of Tughlakabad Fort and gives a hint of glory that once was. The three sections of fort which can be noticed are:
- the wider city area with houses built along a rectangular grid between its gates.
- the citadel with a tower at its highest point known as Bijai-Mandal and the remains of several halls and a long underground passage.
- the adjacent palace area containing the royal residences. A long underground passage below the tower still remains.
