Features of Kerala temples attract world-wide attention. This is mainly because of its unique architectural style and forms. Kerala temples emphasize horizontal monuments as symbolic of the path towards truth. The temple is not a mountain, although it is built around an axis. It is activated by its enshrined `engine`, a holy power in the form of a sculpture or symbol from which energy of goodness radiate. It can be said that perhaps Kerala houses the maximum number of religious buildings. The materials used for the divine buildings are natural and clearly earth-derived. The monument touches the masses in terms of earthly experience rather in the form of worldly grandeur and pomp. An important aspect of Kerala is the profuse use of wood. The divine buildings of Kerala are especially known for their accomplishments in wood. Rather it can be said that in Kerala , the medieval environment of temples in wood, stone, and tile is still alive. About the temples in Kerala can be said that geometric impact of Kerala temple structures, particularly their roofs, is unique. Other buildings in India make strongly geometrical visual statements but nowhere else is the structure as straightforward and abbreviated as in Kerala . It is as if the temple in Kerala has been distilled to its purest ingredients. The rise of temples also saw the development of culture in all its aspects. The temple became the nerve- centre of all cultural activities. Temple festivals were instituted with a view to making the Hindu religion more attractive. Festivals also gave an opportunity to people for the expression of their deepest spiritual cravings. A unique feature of Kerala temples are the classic temples. A classic temple in Kerala is also called ambalam or kshetram. The temples have the central shrine as its heart. The srikoil plan may be round, square, rectangular, or apsidal. Some of them face west and a few face south. Some even reach heights of many roofs. However, the upper levels of the srikoil are not functional; their role is to give the building an imposing appearance.
.In the classical temples of Kerala with the srikoil forming the nucleus, the other components like the open pradakshina patha, the cloistered nalambalam, the vilakkumatam affixed with a galaxy of lamps, paved outer pradakshina van and prakara or prakaras are aligned in orderly succession centering the main shrine or shrines. The, temple well which supplies water for bathing the deity and for preparing food is situated generally in the north-east corner. The kitchen or mada-palli is alsoprovided in one portion of the nalambalam. As a general rule, the srikoil is fronted by a square namaskara mandapa with a pyramidal roof. In some temples there is another pillared structure, the balikkal mandapa, in front of the valiambalam, a wing of the nalambalam, providing the main entrance to the temple proper. Facing the balikkal mandapa, which enshrines the main balipitha is the dwajastambha or flag staff that stands towering over the temple environs. There may be a deepastambha or gallery of lamps also, one or more in number, in front of the balikkal mandapa. Close by, in bigger complexes there is a large edifice, the kuttambalam meant for kuttu or Kutiyattam. Surrounding the inner structure is the paved processional path in the classical temples of Kerala . Then there is the outer prakara (enclosure wall) enclosing all these structures which is pierced at the entrance and sometimes on all four sides by gopuras with multiple roofs covered with tiles though they are not tall or imposing like those of Dravidian shrines. There is also the temple-tank as part of the structure which devotees can use and directly enter the temple after a bath. In almost all the classical temples of Kerala there are small shrines dedicated to Sasta, Lord Ganesha , etc. But more prominently, the sacred trees and snake-stones also survive inside the temple precincts as relics of early animistic devotion.
