rio tejo

Known as Rio Tejo in Portuguese, the Tagus River in Lisbon is one of the longest rivers in the Iberian Peninsula, with a length of 1,038 km. From eastern Spain in Sierra de Albarracín, the river flows through the west across Spain and Portugal.

Rio Tejo flows across Portugal for 179 km. From north of Portugal, it then flows into the Atlantic Ocean near Lisbon. 

The river in Lisbon has been an important spot for both Spain and Portugal’s economic development. It also provides a great view for residents to enjoy. 

The 275 km of the river in Portugal is used for farm irrigation for the Alentejo region.

Both the estuary and the river itself offer a great view of the capital city Lisbon. 

Let’s discover the history and the importance of this great river in more detail.

Historical Background of the River Tagus

Before the name Tagus, this hanging bridge was called Antonio Salazar. The Tagus Bridge then took its name from the 1974 military coup. 

The Vasco da Gama Bridge also takes place across the Tagus River. The Portuguese navigator Vasco da Gama is the reason for the naming of the bridge. 

The Tagus bridge was built in 1998. It’s also the longest bridge in Europe with a length of 17.2 km, built within 1,5 years. It stretches from eastern Lisbon to the west bank of the Tagus River estuary. Tagus Bridge is also able to withstand hurricanes up to 250 km/h and earthquakes. 

While designing the bridge, they also considered energy efficiency and the environment. For this reason, the lamps of the bridge lighten up only the roadway and not the river.

The Portuguese government also considered the issue of hydroelectrical power and irrigation. To this end, over 60 dams were built between 1960 and 1980. In this way, the river helps irrigate the arid areas around it. The generation of hydroelectric power from the river also contributes to the country’s economy as well. 

About the River Tagus

We’ve mentioned the dams built around the river above. The installed power capacity of these aforementioned dams is more than 1,200,000 kilowatts. 

One of Lisbon rivers, the River Tagus basin is also home to coniferous trees that contribute to the timber industry. A certain division of the cultivated land is used for cereal farming as well. Vineyards and olive trees are also available. 

There are also diverse animal species including that of European and North African.
