I don’t know if images still work in these forms, but I thought you both might enjoy a photo of the inside of the Basílica de la La Sagrada Familia in Barcelona, Spain. My wife and I visited it in 2017 during an international trademark convention.
One side of the Cathedral stain glass reflects only the red spectrum side of the sunrise light, and the other reflects the blue spectrum of the sunset light.
I can send a picture of the unique outside of it, if you wish. We were able to climb the circular stair in one of the towers as well. The organic Gothic architecture was done by Spanish architect Antoni Gaudí (1852–1926).
Wikepedia search “Sagrada Família” for more info.
