The geographical location of Aranjuez, in the confluence of the biggest river of the Iberian peninsula, the Tajo, and its main affluent, the Jarama, it has labeled the historical existence of the Royal Place, and its peculiar climate and vegetation.
In the context of the castillan plateau, Aranjuez appears as a leafy island of natural wild wealth, thanks to the abundance of water and to the fertility of sedentary soils of the valley that form both rivers.
The history of Aranjuez is the history of the Tajo and the effort by mastering the rivers: to contain them, to cross them, to retain them, to navigate them.
