In which city would you find the Tagus River?
Answer
Lisbon
Answer
Lisbon
You would find the Tagus River in Lisbon. The river reaches the Atlantic Ocean through the broad Tagus estuary beside Portugal’s capital, making Lisbon one of its most recognizable city landmarks.
The Tagus is the Iberian Peninsula’s longest river, running for roughly 1,000 kilometers from its source in eastern Spain across central Spain and Portugal. It passes important Spanish cities such as Toledo before flowing through Portugal toward Lisbon.
Lisbon developed around the river’s northern bank, and the Tagus shaped the city’s history as a major port during Portugal’s Age of Discoveries. Explorers’ ships departed from the river for voyages to Africa, Asia, and the Americas.
A common mix-up is the Douro River, which is associated with Porto farther north. The Tagus is also called the Tajo in Spanish and the Tejo in Portuguese; these are different names for the same river.
