The city of Sirsa and its surrounding areas is a haven of the rich historical and cultural heritage of the Ghaggar valley. This was discovered by the Archaeological Survey of India through its excavations at 54 sites close to Ghaggar River in the years 1967 and 1968. The rich haul of discoveries consisted of painted potted ware such as dishes and bowls of various designs and colors belonging to Rang Mahal Culture.
The three major historical sites discovered by the Archaeological Survey of India in Sirsa were:
Sikandarpur: Two mounds located one mile away from each other lie around 12 kms to the east of Sirsa. The discoveries included heavy stone slabs, a sculpture of Indra and "Ekmukha Linga" of Shiva, specimens of a medieval temple and pottery ware of Rang Mahal times.
Suchan: Situated 16 kms east of Sirsa, the mound unfolded the early medieval pottery pieces of Rang Mahal.
