Sagrada Família. A WOW experience
These stained-glass windows are inside the Sagrada Família in Barcelona, on the Nativity side of the basilica, and their colors were not chosen by accident.
Gaudí set the rule before he died in 1926, decades before this part of the nave was even built: morning light on this side, facing east, should pass through blue and green glass, evoking dawn and new life, matching the birth of Christ carved into the facade just outside this wall.
On the opposite side of the building, behind the Passion facade, the glass turns warm instead: reds, oranges and golds for the afternoon sun, echoing sacrifice and fire. Same basilica, two completely different moods depending on which side you're standing on and what time you show up.
The glass itself was designed by Joan Vila-Grau, a Catalan painter and master glazier who started the project in 1999 and spent more than twenty years finishing it, working from Gaudí's original notes rather than inventing his own scheme.
Time it right and the effect gets stronger. Around the summer solstice, morning sun lines up almost perfectly with these Nativity side windows, throwing pools of blue and green light across the columns and floor. The same thing happens on the Passion side around the winter solstice, but in fiery red.
