The picture shows the inside of the University in Wrocław. Better: The department of polish philology.
For me as an economist, it was always unclear how people can dedicate their life to their language and literature. But especially if you got taught a bit about polish history, you know how important that was and still is.
One of the main reason we have a polish state today, is because the polish people always kept their language, even if their state wasn’t existing for a long time. So if you know that, you get a feeling that this building of the university might be one of the most important places for the nation.
