Valladolid (province) in the context of "Province of Burgos"

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.

Palencia is a province of northern Spain, in the northern part of the autonomous community of Castile and León in the north of the Iberian Peninsula. It is bordered by the provinces of León, Cantabria, Burgos, and Valladolid.

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.
