A green oasis at the foot of the Andes

Mendoza's streets are laid out in neat straight lines.

Small water channels run beside them to water thousands of trees.

Universalis describes Mendoza as an airy city with streets laid out in a grid, lined with thousands of trees that are watered by small irrigation channels. The old colonial town was destroyed by an earthquake in 1861.

Since 1880, rich irrigated farmland has been developed at the foot of the Andes around Mendoza, and Universalis calls the city the leading center of those farming areas.

Universalis: an airy city with an orthogonal plan underlined by thousands of trees bathed by irrigation channels; the colonial city was totally destroyed by the earthquake of 1861; the agglomeration is the undisputed metropolis of the rich irrigated areas developed since 1880 at the foot of the Andes of Cuyo, and Mendoza has real mastery of the techniques of development and production in irrigated land; it has kept a population that the relative prosperity of Cuyo does not push to emigrate.
