The fort of Sher Shah Suri at Rohtasgarh is in Sasaram. This fort has a history dating back to the 7th century AD. It was built by Raja Harishchandra, known for his truthfulness in the name of his son Rohitashwa. It houses the Churasan temple, Ganesh temple, diwan-e khas, diwan-e-aam, and various other structures dating back to different centuries. The fort also served as the headquarters of Raja Man Singh during his reign as the governor of Bihar and Bengal under the regime of Akbar. The Rohtaas fort in Bihar should not be confused with another fort of the same name, near Jhelum, Punjab, in what is now Pakistan. The Rohtaas fort in Sasaram was also built by Sher Shah Suri, during the period when Humayun was exiled from Hindustan.
