Ávila (province) in the context of "Pico Almanzor"

Valladolid (Spanish: [baʎaðoˈlið] ) is a province of northwest Spain, in the central part of the autonomous community of Castile and León. It has a population of 525,398 across a total of 225 municipalities, an area of 8,110 km (3,130 sq mi), meaning a population density of 64.77 people per km.

The capital is the city of Valladolid. It is bordered by the provinces of Zamora, León, Palencia, Burgos, Segovia, Ávila, and Salamanca. It is the only Spanish province surrounded entirely by other provinces of the same autonomous community. It is the only peninsular province which has no mountains.

Old Castile (Spanish: Castilla la Vieja [kasˈtiʎa la ˈβjexa]) is a historic region of Spain, which had different definitions across the centuries. Its extension was formally defined in the 1833 territorial division of Spain as the sum of the following provinces: Santander (now Cantabria), Burgos, Logroño (now La Rioja), Soria, Segovia, Ávila, Valladolid and Palencia. As the rest of regions in that division, Old Castile never had any special administrative agency; only the individual provinces had their own management.

The name Old Castile reflects the fact that this territory corresponds very roughly to the extension of the Kingdom of Castile around the 11th century, before it expanded to the south. This kingdom had its origins in the 9th century in an area now comprising Cantabria, Álava, and Burgos province.

Segovia (Spanish pronunciation: [seˈɣoβja] ) is a province of central/northern Spain, in the southern part of the autonomous community of Castile and León. It is bordered by the province of Burgos in the north, Soria in the northeast, Guadalajara in the east, Madrid in the south, Ávila in the west and southwest, and Valladolid in the northwest. The average temperature ranges from 10 °C to 20 °C.

The Tormes is a Spanish river that starts in Prado Tormejón, in the mountain range of Gredos, Navarredonda de Gredos, province of Ávila. It crosses the provinces of Avila and Salamanca, ending at the Duero River, at a place known locally as Ambasaguas, after 284 kilometres (176 mi). This river is not able to provide the water supply to the population during summer, and for this reason, the dam of Santa Teresa was constructed in 1960 with a capacity of 496 million cubic metres (402,000 acre⋅ft) to regulate and assure the water supply in summer as well as moderate high flows in winter. Also, it has the dam of Villagonzalo and the Almendra Dam, near where it joins the Duero. Due to limitations in providing water supply to the population during summer, the Tormes River plays a crucial role in water management through its dams.
