The Mauryan period is considered as the beginning of the classical period of Indian architecture. Nagara and Dravidian architectural styles developed in the early medieval period with the rise of Hindu revivalism and predominant role of Hindu temple architecture in the Indian Subcontinent.
From ancient South Indian temples to the finest Mughal ruins, Indian architecture is as old as civilization itself. The earliest traces of recognizable building activity in India can be traced back to the settlements of the Indus Valley.
