Development can be seen as a constant factor of change in a landscape of one's place. And one of the visible icon of this change is the "plaza" of a certain place.
Plaza is a colonial concept similar to a market place influenced by the Spanish. It is actually a place for people to take some time to relax like breathing a fresh air (in a rural areas, if speaking of "fresh air"). Like any other "plaza", rural plaza is simpler than the urban plazas, but that depends on the area available for development.
