Hindu temple architecture as the main form of Hindu architecture has many different styles, though the basic nature of the Hindu temple remains the same, with the essential feature an inner sanctum, the garbha griha or womb-chamber, where the primary Murti or the image of a deity is housed in a simple bare cell. For rituals and prayers, this chamber frequently has an open space that can be moved in a clockwise direction. There are frequently additional buildings and structures in the vicinity of this chamber, with the largest ones covering several acres. On the exterior, the garbhagriha is crowned by a tower-like shikhara, also called the vimana in the south. Gopuram gateways are elaborate in the south. These are topped with a finial called kalasha. The shrine building often includes an circumambulatory passage for parikrama, a mandapa congregation hall, and sometimes an antarala antechamber and porch between garbhagriha and mandapa. In addition to other small temples in the compound, there may be additional mandapas or buildings that are either connected or separate from the larger temples.
