A large Dravidian-style temple, or koil, may have multiple gopurams as the openings into successively smaller walled enclosures around the main shrine, with the largest generally at the outer edges. The temple compound is typically square or rectangular with at least the outermost wall having gopuras, often from the four cardinal directions. The multiple storeys of a gopuram typically repeat the lower level features on a rhythmic diminishing scale. The inner sanctum and its towering roof (the central deity's shrine) is also called the "Vimanam", although in the south it is typically smaller than the gopurams in large temples.
