The following points explain the development of temples in the Bengal region
→ The temples and various other religious structures were often built by individuals or groups who were becoming powerful to demonstrate their power and proclaim their piety as well.
→ Many of the modest brick and terracotta temples in Bengal were built with the support of several 'low' social groups, like Kolu (oil pressers) and the Kansari (bell metal workers).
→ When local deities gained the recognition of the Brahmanas, their images began to be honoured in temples.
→ The temples began to copy the double roofed or four roofed thatched huts.
→ Temples were built on raised square platforms. Outer walls were decorated with paintings, ornamental tiles or terrocotta tablets. Vishnupur in the Bankura district of West Bengal has a remarkable set of temples decorated with terracotta reliefs.
