Sasaram , sometimes also spelled as Sahasram, is the administrative headquarters of the Rohtas district in the Indian state of Bihar. It is one of the oldest cities in India, and is famous for production of stone chips and also for the local quarrying industry. Languages spoken in this region are Bhojpuri, Hindi, and Urdu; local religions include Islam, Buddhism, Jainism, and Hinduism.
Sasaram is the birthplace of the Afghan king Sher Shah Suri, who ruled over Delhi, much of northern India, what is now Pakistan, and eastern Afghanistan for five years, after defeating the Mughal Emperor Humayun. Sher Shah Suri's 122 feet (37 m) red sandstone tomb, built in the Indo-Afghan style stands in the middle of an artificial lake at 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 Bhuddhist stupa style of the Mauryan period.
