Absolutely stunning cathedral with an interesting history. It's not expensive, but when you scan the QR code, you can listen to its history from your phone as you walk around it, which is an excellent idea! You can not fail to miss the basilica as it is situated in the middle of Leon, surrounded by a plaza with cafes and shops. The basilica was wonderfully cool inside, which is welcome in 35°C heat.
