This property, declared World Heritage as a Cultural Landscape, comprises the urban space of Madrid bounded by the Paseo del Prado and the Retiro Park. UNESCO defines it as a unique model of urban planning ahead of its time, reflecting an ideal of a new society that extended beyond our borders, and an urban cultural landscape carefully designed for the recreation and education of citizens in contact with nature.

The Landscape of Light is, therefore, the first tree-lined promenade in the world to be open to the enjoyment of citizens, without social distinctions, and also the first in a European capital, being the prototype of the Hispanic alameda and a model to be followed by different cities around the world. Both the promenade and the park form an inseparable ensemble whose origin dates back to the mid-sixteenth century, the promenade being the first example of an urban boulevard in which later were located the great cultural, scientific, political, economic and representative institutions of Madrid society and the Spanish State.
