What is the relationship between knowledge and culture?

This is an image of Bilbao, Basque Country in Spain. I was given the opportunity to visit in 2022. The region is distinctly Basque, and not Spanish and they even have their own language. The relationship between knowledge and culture is demonstrated here as we can see how knowledge allows this culture to thrive, despite the hundreds of years of oppression of the Basque people.

The Basque language is believed to be the oldest in Europe, if not, the world, and the fact it has survived Gothic, Latin, Arabic and modern lingual invasions for over 1000 years. We can see that its survival, and the knowledge of it today among Basque people allows the culture to stand and survive as it does today.
