About Bilbao
Bilbao, with a population of about 350,000 (2018, and over a million in the metro area), is the largest city in Spain's Basque Country. Bilbao is perhaps the best place in the world to experience the ancient culture and language of the Basque people, which has stubbornly held its own over thousands of years and is now completely unlike any modern-day culture in Europe.
