La Rioja (Spain) in the context of "Logroño"

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).

The Vascones were a pre-Roman tribe who, on the arrival of the Romans in the 1st century, inhabited a territory that spanned between the upper course of the Ebro river and the southern basin of the western Pyrenees, a region that coincides with present-day Navarre, western Aragon and northeastern La Rioja, in the Iberian Peninsula. The Vascones are often considered ancestors of the present-day Basques to whom they left their name.

Castile and León is an autonomous community in northwestern Spain. Castile and León is the largest autonomous community in Spain by area, covering 94,222 km. It is, however, sparsely populated, with a population density below 30/km. While a capital has not been explicitly declared, the seats of the executive and legislative powers are set in Valladolid by law, and for all purposes that city (also the most populated municipality) serves as the de facto regional capital.

Castile and León is a landlocked region, bordered by Portugal as well as by the Spanish autonomous communities of Galicia, Asturias, Cantabria, the Basque Country, La Rioja, Aragon, Castilla–La Mancha, the Community of Madrid and Extremadura. Chiefly comprising the northern half of the Inner Plateau, it is surrounded by mountain barriers (the Cantabrian Mountains to the North, the Sistema Central to the South and the Sistema Ibérico to the East) and most of the territory is drained by the Douro River (Spanish: Duero), flowing west toward the Atlantic Ocean.

The Pellendones, also designated Pelendones Celtiberorum and Cerindones, were an ancient pre-Roman Celtic people living on the Iberian Peninsula. From the early 4th century BC they inhabited the region near the source of the river Duero in what today is north-central Spain, an area comprising the north of Soria, the southeast of Burgos and the southwest of La Rioja provinces.

The mineral pyrite (/ˈpaɪraɪt/ PY-ryte), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS₂ (iron (II) disulfide). Pyrite is the most abundant sulfide mineral.

Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and brazil, primarily used to refer to pyrite found in coal.

Miranda de Ebro (Spanish: [miˈɾan̪da ðe ˈeβɾo]) is a Spanish municipality belonging to the province of Burgos in the autonomous community of Castile and León. Straddling the Ebro river, near its confluence with the Bayas, the city is located on the northern watershed of the Obarenes Mountains, near the border with the Basque province of Álava and the autonomous community of La Rioja. As of 2 January 2025, the municipality has a registered population of 37,138.

The city has an industrial economy focusing on the chemical industry. Connected to the Meseta Central through the Pancorbo Pass [es], Miranda is an important transportation hub, served by the AP-1 and AP-68 road routes and the Madrid–Hendaye and Tudela–Bilbao rail routes. Within 80 kilometres (50 miles) are the cities of Bilbao, Burgos, Logroño and Vitoria-Gasteiz.
