Spain culture!

Can someone tell me about the culture of Spain? I’m writing a book and the MC is a foreign exchange student. She’s from Spain. I want to learn about the culture there because I’ve never been I’m looking up some stuff but I want to learn as much as I can so I won't disrespect anyone who reads the book and most importantly the culture.

it can be about anything, it might be a stupid question but i just want to have knowledge on the topic 😭.
