The main temple at Konark, locally called the "deul", no longer exists. It was surrounded by subsidiary shrines containing niches depicting Hindu deities, particularly Surya in many of his aspects. The "deul" was built on a high terrace. The temple was originally a complex consisting of the main sanctuary, called the "rekha deul", or "bada deul" (lit. big sanctum). In front of it was the "bhadra deul" (lit. small sanctum), or "jagamohana" (lit. assembly hall of the people) (called a "mandapa" in other parts of India.). The attached platform was called the "pida deul", which consisted of a square "mandapa" with a pyramidal roof. All of these structures were square at their core, and each was overlain with the "pancharatha" plan containing a variegated exterior. The central projection, called the "raha", is more pronounced than the side projections, called "kanika-paga", a style that aims for an interplay of sunlight and shade and adds to the visual appeal of the structure throughout the day. The design manual for this style is found in the "Silpa Sastra" of ancient Odisha.
