The Ghateshwara Mahadeva temple is the most prominent and the largest in the complex. The main temple structure comprises the sanctum (garbhagriha) and the mukhamandapa, a front mandapa or hall. Dated to the early 10th century, it is an intact structure which has the god Shiva depicted in the form of five lingas. One linga appears like an inverted ghata or pot, and hence the name given to the temple of "Ghateshwara" (pot-Lord), while "Mahadeva" is a term for Shiva. The sanctum has a ceiling in the form of a large blossoming lotus. The temple has a finely carved shikara(pinnacle) above the sanctum. The superstructure has been described as a latina and the pinnacle is a phamsana. The entire superstructure is supported by six pillars and two pilasters. The pilasters, which are part of the sanctum wall, project from the wallby two thirds of its width, and have niches encased with sculptures.
