Álava ( in Spanish) or Araba ( in Basque), officially Araba/Álava, is a province of Spain and a historical territory of the Basque Country, heir of the ancient Lordship of Álava. Its capital city is Vitoria-Gasteiz which is also the seat of the political main institutions of the autonomous community. It borders the Basque provinces of Biscay and Gipuzkoa to the north, the community of La Rioja to the south, the province of Burgos (in the community of Castile and León) to the west and the community of Navarre to the east. The Enclave of Treviño, surrounded by Alavese territory, is part of the province of Burgos and, so, belongs to the autonomus community of Castile and León, not Álava.
