Hindu temples are primarily built to house the deity and facilitate worship. They are considered sacred spaces where devotees can offer prayers, seek blessings, and perform rituals.

The main architectural features of a typical Hindu temple include a sanctum sanctorum (the innermost chamber where the deity is housed), a mandapa (a pillared hall for congregational worship), and a shikhara (the towering spire above the sanctum sanctorum).

The temple tower or shikhara has multiple significances. It represents the abode of the deity, serves as a landmark for pilgrims, and enhances the aesthetic appeal of the temple.

Sculptures and carvings in Hindu temples serve multiple purposes. They depict scenes from mythology and religious texts, act as a form of decoration, and convey moral lessons and teachings.

Hindu temples contribute to the cultural identity of India by showcasing the country's rich architectural heritage, reflecting the diverse religious beliefs and practices of India, and serving as centers of community gatherings and festivals.
