Compared to other European (and other) cathedrals/churches I have visited, this one is very unique…read more The ceiling is covered with a colorful and beautiful mosaic depicting numerous Biblical scenes (both OT and NT). It also contains an enormous and beautiful organ, along with a large altar. All of the artifacts and decor here work very well together, and the building is beautiful.
One recommendation I have is to check out the QR codes. They give you a great description and historical context of the different scenes in the church, and you can learn a lot from them.
