English: Arjuna's Ratha -one among the five ratha's from mamallapuram . The Arjuna ratha is a two-tired temple, with a square section in both the tiers, an octagonal shaped "Griva" (neck) and "Sikara" (head). "Karnakutas" (a hara structure kept at four corners above the roof of the first tier) and "Salas" (in the form of a boat or a bullock cart placed at the center on all four sides), have been introduced in this temple. The "Karnakutas" and the "Salas" above the roof are together called a "Hara". Another innovation in this temple is the lower tier, which starting from the basement is split vertically with projections at equal intervals. These projections divide the structure into compartments called "Bhadras" with depressions in between.
