History
Like the other four Pancha Rathas, Dharmaraja ratha was built from stone, a replica of a wooden version which preceded it. The temple is incomplete.
Architecture
All the Pancha Rathas are aligned in a north-south direction and share a common plinth. They have no precedent in Indian architecture and have proved to be "templates" for building larger temples in the SouthIndian tradition of Dravidian temple architecture. Though cut out of monolithic rocks, they are carved in the form of structural temples in regular building form and hence termed as "quasimonolithic temple form. Dharmaraja Ratha is the most prominent architecturally of the five rathas and also the tallest and largest. The ratha faces west and is sculpturally very rich. It has three floors including the ground floor. The plan of the ground floor measure a square of and has a height of from ground level to the top of the roof. It is open on all four sides and the facade on all sides are supported by two pillars and two pilasters with the corners forming an integral part of the support system for the upper floors. Carved out from a single rock of pink granite, along with other three rathas on a single block of stone oriented in a north-south direction, it is a trithala or three-story vimana, square in plan, with open porches and a terraced pyramidal tower. and an octagonal shikhara at the top. Small-sized model shrines called kudus make up the ornament of the upper part of the tower. There are many sculptures on the corners of the sanctum, which depict Shiva; Harihara, Brahma-Sasta, Skanda, Brahma, Ardhanarisvara and Krishna are depicted alongside an inscribed portrait of a king, indicated to be Narasimhavarman I, who commissioned the temple. The shafts of the pillars are supported by seated lions. The second floor contains rich imagery, with further depictions of Shiva as Gangadara and Natesa, and Vishnu resting on Garuda and Kaliya Mardhana.
Inscriptions
On the Dharmaraja Rathas there are 16 inscriptions in Grantha and Nagari scripts in Sanskrit inscriptions on which are royal cognomen, single-word titles, most of them are attributed to Narasimhavarman I.
