Sri Surya Deva (the original sanctum deity; no longer present; ASI-protected); the original design form: 12-pair (24-total) chariot wheels + 7 horses (sun-chariot architecture); upashalas: Mayadevi Temple (late-11th century; pre-dates the main temple — flag), Vaishnava Temple (discovered 1956), Natamandira + Bhogamandapa (ruined)
Sun-chariot architecture: 12-pair (24-total) chariot wheels (~3.7 m / 12 ft diameter each; the Shukla + Krishna paksha pairing = 12 months); 7 horses (named after Sanskrit prosodic meters: Gayatri + Brihati + Ushnih + Jagati + Trishtubh + Anushtubh + Pankti — the Wikipedia text-supported interpretation; the popular '7 days of the week / 7 colours' reading has no textual source — flagged); the chariot-wheel sundial is accurate to the minute (8 major spokes per wheel; widely cited)
सम्प्रदाय: Solar / Surya upasana; in the modern era: an ASI-protected monument (no longer in worship; the Jagamohana was sand-filled in 1903 by the ASI); an Eastern-Ganga-dynasty-built historical monument
