Editing Tagus (section)

== Historical importance ==

In addition to its geographical relevance, the Tagus has great historical importance, resulting from its connection with Toledo and Lisbon, two of the cities with the greatest weight and historical journey in the Iberian Peninsula. The first was built on a hill about 100 m high, around the meander known as Torno del Tajo, which preserved it from possible attacks and incursions.

From the Late Middle Ages, the mouth of the Tagus articulated an intense commercial activity between Northern Europe and the Mediterranean. From the Renaissance, it was the main communications hub of the Portuguese Empire, which extended through America, Africa, and Asia.
