Spain. Basque Country. Bilbao is the largest city in the province of Biscay and in the Basque Country as a whole. Wedding celebration. Dance party. Couples laugh and hold hands. The Basque Country or Basque Autonomous Community was granted the status of nationality within Spain, attributed by the Spanish Constitution of 1978. The autonomous community is based on the Statute of Autonomy of the Basque Country, a foundational legal document providing the framework for the development of the Basque people on Spanish soil. 20.03.92 © 1992 Didier Ruef
