Sasaram was once also named Shah Sarai (meaning "Place of the King"), as it is the birthplace of the Afghan king Sher Shah Suri, who ruled over Delhi, much of northern India, present-day Pakistan, and eastern Afghanistan for five years as the Sur Empire, after defeating the Mughal Emperor Humayun.

Sher Shah Suri's 122-foot (37 m) red sandstone tomb, built in the Indo-Afghan style, stands in the middle of an artificial lake in Sasaram.

It borrows heavily from the Lodhi style, and was once covered in blue and yellow glazed tiles, indicating an Iranian influence.

The massive free-standing dome also has an aesthetic aspect of the Buddhist stupa style of the Mauryan period.

The tomb of Sher Shah's father, Hasan Khan Suri, is also at Sasaram, and stands in the middle of a green field at Sherganj, which is known as Sukha Rauza.

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 Rohtas Fort in Sasaram was also built by Sher Shah Suri, during the period when Humayun was exiled from Hindustan.

Rohtas, south of Sasaram, is known to have been the residence of one Satyawadi Raja Harischandra, named for his son, Rohitashwa.

Sasaram is also famous for an inscription by Ashoka (one of the thirteen Minor Rock Edicts), situated in a small cave of Kaimur hill, near Chandan Shaheed.

SAHAJ Vasudha Kendra, the first "Common Service Centre", or "eKiosk", in Rohtas District was inaugurated in Jamuhar village on 15 August 2008.

However, now this AC train runs between Gaya and Anand Vihar Terminal, still stopping at Sasaram Junction.

Indian Railways had a 24-hour power supply at Sasaram junction, leading a small group of students to study there at night under electric lights.
