As the stupas became the religious sites of Buddhism, a similar number of temples were constructed to house the Hindu deities. The earliest constructed temple used to have small square rooms, that came to be known as the garbagriha. This garbagriha used to house the principal deity. These garbagrihas used to have a single doorway from which the worshipper enter and offer his prayers to the deity. A tall structure known as the Shikhara was constructed over the principal shrine. This Shikhara gave a royal look to the temple. The walls of the temple was generally decorated with sculptures to enhance the beauty of the structure. Gradually, numerous features of the temples came into existence, such as assembly halls, huge walls and gateways, arrangements for supplying water.
