The Tagus (/ˈtɡəs/ TAY-gəs; Spanish: Tajo [ˈtaxo]; Portuguese: Tejo [ˈtɛʒu]; see below) is the longest river in the Iberian Peninsula. The river rises in the Montes Universales near Teruel, in mid-eastern Spain, flows 1,007 km (626 mi), generally westward, and empties into the Atlantic Ocean in Lisbon.[1]

Name[edit]

The river's Latin name is Tagus. While the etymology is unclear, the most probable etymological origin for the hydronym Tagus is Indo-European *(s)tag- ('to drip').[2]

Geology[edit]

The lower Tagus region in Portugal is a seismically active area. Major earthquakes in the Lower Tagus include those of 1309, 1531, and 1909.[3][4]

History[edit]

Tagus river seen from the Castle of Almourol, Portugal.

The Pepper Wreck, properly the wreck of the Nossa Senhora dos Mártires, is a shipwreck located and excavated at the mouth of the Tagus between 1996 and 2001.[5]

The Tagus river basin comprises 42 River Nature Reserves [es] and is the river basin with the most protected areas in Spain.[1]: Prefacio
