The site of a place is a factor that influences the choice of settlements. It refers to the characteristics of a place like topography, altitude, the characteristics of water bodies, types of soil, security, and shelter from natural forces. For example, the Fort built by Maharaja Chhatrapati Shivaji at Pratapgadh in Maharashtra offered a panoramic view of hundreds of kilometres from the Fort and provided a great military advantage.
