Sisupalgarh Archaeological Site

Sisupalgarh Archaeological Site is the remains of an ancient fortified city located on the southeastern outskirts of Bhubaneswar in Khordha district, Odisha. Enclosed by earthen ramparts forming a quadrangle, it is one of the largest and best-preserved early historic fortifications in India. Excavations have revealed gateways, moats, and habitation deposits dating from the 3rd century BCE to the 4th century CE, associated with the Mauryan and post-Mauryan periods.

Visitors can expect a large open archaeological area defined by high earthen ramparts forming a square plan with traces of a surrounding moat. The site contains remains of eight gateways, including two elaborate northern gateways, and the area known as Shola Khamba with sixteen laterite columns. The interior is largely open fields with scattered mounds and excavated trenches. There are no reconstructed buildings; the experience is of exploring ancient earthworks, gateway foundations and column remains in a rural setting on the edge of Bhubaneswar.

Sisupalgarh is an early historic fortified city dating from around the 3rd century BCE to the 4th century CE. Excavations by B.B. Lal in 1948 and later joint Deccan College and University of California teams revealed a planned quadrangular settlement with glacis, moat and gateways. It is identified by many scholars with ancient Tosali or Kalinganagara and shows Mauryan and post-Mauryan urban planning, with evidence of continuous habitation through the Shunga, Satavahana and Gupta periods.

The site represents early urbanization in eastern India and Kalinga's historic urban tradition. Its defensive architecture, gateway design and column structures illustrate ancient town planning and construction techniques. It is protected as a centrally protected monument by the Archaeological Survey of India and is significant for understanding the cultural history of the Bhubaneswar region.
