Douro in the context of "Ebro river"

The Ebro (Spanish and Basque [ˈeβɾo] ; Catalan: Ebre, Western: [ˈeβɾe], Eastern: [ˈeβɾə]) is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows 930 kilometres (580 mi), almost entirely in an east-southeast direction. It flows into the Mediterranean Sea, forming a delta in the Terres de l'Ebre region, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal.

The Ebro flows through many cities (Spanish: ciudades): Reinosa in Cantabria; Frías and Miranda de Ebro in Castile and León; Haro, Logroño, Calahorra, and Alfaro in La Rioja; Tudela in Navarre; Alagón, Utebo, and Zaragoza in Aragon; and Flix, Móra d'Ebre, Benifallet, Tivenys, Xerta, Aldover, Tortosa, and Amposta in the province of Tarragona (Catalonia).

Celtiberian or Northeastern Hispano-Celtic is an extinct Indo-European language of the Celtic branch spoken by the Celtiberians in an area of the Iberian Peninsula between the headwaters of the Douro, Tagus, Júcar and Turia rivers and the Ebro river. This language is directly attested in nearly 200 inscriptions dated from the 2nd century BC to the 1st century AD, mainly in Celtiberian script, a direct adaptation of the northeastern Iberian script, but also in the Latin alphabet. The longest extant Celtiberian inscriptions are those on three Botorrita plaques, bronze plaques from Botorrita near Zaragoza, dating to the early 1st century BC, labeled Botorrita I, III and IV (Botorrita II is in Latin). Shorter and more fragmentary is the Novallas bronze tablet.

Porto, officially the Ancient, Very Noble, Ever Loyal and Undefeated City of Porto, also known in English as Oporto, is the second largest city in Portugal, after Lisbon. It is the capital of the Porto District and one of the Iberian Peninsula's major urban areas. Porto city proper, which is the entire municipality of Porto, is small compared to its metropolitan area, with an estimated population of 252,687 people in a municipal area of 41.42 km (16 sq mi). As of 2025, Porto's urban area has around 1.4 million people in an area of 2,395 km (925 sq mi), making it the second-largest urban area in Portugal. while the Porto metro area has more than 1.8 million people. It is recognized as a global city with a Gamma + rating from the Globalization and World Cities Research Network.

On the Douro River estuary in northern Portugal, Porto is one of the oldest European centers, and its core was named a World Heritage Site by UNESCO in 1996, as the Historic Centre of Porto, Luiz I Bridge and Monastery of Serra do Pilar. The historic area is also a National Monument of Portugal. The western part of its urban area extends to the coastline of the Atlantic Ocean. Settlement dates back to the 2nd century BC, when it was an outpost of the Roman Republic. Its combined Celtic-Latin name, Portus Cale, has been referred to as the origin of the name Portugal, based on transliteration and oral evolution from Latin.

Tordesillas (Spanish pronunciation: [toɾðeˈsiʎas]) is a town and municipality in the province of Valladolid, Castile and León, central Spain. It is located 25 kilometres (16 mi) southwest of the provincial capital, Valladolid at an elevation of 704 m (2,310 ft). The population was c. 8,760 as of 2021.

The town is located on the Douro River although the river is not navigable at that point. Highways connect to Madrid (182 km (113 mi) southeast) and Salamanca (96 km (60 mi) southwest). The provincial capital Valladolid is also linked by four-lane highway. Because of its important highway connections Tordesillas has become a major transit hub. The economy is based on services—especially connected to tourism—and the agricultural production of the surrounding area. Wheat has long been the traditional agricultural product (see Cuisine of the province of Valladolid).

The Numantine War (from Bellum Numantinum in Appian's Roman History) was the last conflict of the Celtiberian Wars fought by the Romans to subdue those people along the Ebro, in what is now Spain. It was a twenty-year conflict between the Celtiberian tribes of Hispania Citerior and the Roman government. It began in 154 BC as a revolt of the Celtiberians of Numantia on the Douro. The first phase of the war ended in 151, but in 143, war flared up again with a new insurrection in Numantia.

The first war was fought contemporaneously with the Lusitanian War in Hispania Ulterior. The Lusitanians were subdued by Sulpicius Galba, who betrayed their surrender and executed their leading men, and the Arevaci of Hispania Citerior continued the war and allied with the Lusitanian leader Viriathus.

The Iberian System is one of the major systems of mountain ranges in Spain.It consists of a vast and complex area of mostly relatively high and rugged mountain chains and massifs located in the central region of the Iberian Peninsula, but reaching almost the Mediterranean coast in the Valencian Community in the east.

The system is hydrographically important, as it separates the watersheds of most of the major rivers in Spain and Portugal, including the Ebro basin to the east from the basins of the Douro, Tagus, Guadiana (Záncara-Gigüela), Júcar and Turia to the west and south.

Lusitanian (so named after the Lusitani or Lusitanians) was an Indo-European Paleohispanic language. There has been support for either a connection with the ancient Italic languages or Celtic languages. It is known from only six sizeable inscriptions, dated to roughly the first century AD, and numerous names of places (toponyms) and of gods (theonyms). The language was spoken in the territory inhabited by Lusitanian tribes, between the Douro and Tagus rivers, territory that today falls in central Portugal and western Spain.

The Pisuerga is a river in northern Spain, the Duero's second largest tributary. It rises in the Cantabrian Mountains in the province of Palencia, autonomous region of Castile and León.Its traditional source is called Fuente Cobre, but it has been discovered that the real source is a glacier higher in the mountains. The river flows south into the Douro river shortly after passing through the city of Valladolid. Its length is approximately 270 kilometres (170 mi).

Since the 1950s the water level of the river has been very regular throughout the year due to the huge Aguilar de Campoo dam which collects all the water from the river's rainy upper valleys. This regulation has allowed the creation of vast extensions of irrigated farmland along the Pisuerga's course across the northern Castilian plain.
