Translation Services in San Sebastián

San Sebastián/Donostia

San Sebastián, or Donostia in Basque, is the capital city of the province of Guipúzcoa, in the autonomous community of the Basque Country. It has 180,000 inhabitants (over 400,000 including the metropolitan region), and is located in the Gulf of Vizcaya, 20 km from France.

Tourism is a mainstay of the local economy, as industry is scarce and is based in other areas of the province. The decision of the royal family to choose San Sebastián as a holiday destination was what sparked this activity, which also had an influence on the city’s architectural design (the Maria Cristina Hotel and the Victoria Eugenia Theatre are good examples). The promotion of tourism continues and multiple summer festivals are held every year. Commerce has also been ever-present in the city’s history, particularly in Avenida de la Libertad and the nearby area, which boast a large number of banks and major stores.
