Outside the Langar Khani Gate is the tomb of a lady called Khair Un Nisa. She was the daughter of the food minister named Qadir Bukhsh. She died here and was buried in this tomb but she was later moved to Sasaram.

Until the construction of the new Grand Trunk Road, Rohtas was a halting place on the main Peshawar-Lahore road. This road had serais about a mile apart. One of these is about one mile (1.6 km) north of the Rohtas Fort. It is in a fair state of preservation.
