What country is Aragón in?

Could you please elaborate on the geographical location of Aragón? I'm curious to know which country it belongs to. Is it located in Europe, Asia, or perhaps some other continent? If it's in Europe, I'd appreciate it if you could narrow it down further, perhaps mentioning its neighboring countries or any significant landmarks nearby. Additionally, any historical or cultural context about Aragón would be interesting to learn as well. Thank you for your assistance in clarifying this geographical query.
