Sagrada Família's Agnus Dei lit by concealed UV tech

architecture-design · 2026-07-23

Moritz Waldemeyer, a designer and 'art engineer' based in London, has created a striking lighting feature for Andrea Mastrovito's glass piece, Agnus Dei, showcased at the Sagrada Família in Barcelona. This project, commissioned by the Junta Constructora de la Sagrada Família, reflects Antoni Gaudí's original vision through Mastrovito's detailed glass lamb. Located at the top of the 172-meter Tower of Jesus Christ, Waldemeyer introduced a cutting-edge ultraviolet lighting system that activates phosphorescent pigments, allowing the lamb to glow without visible light. This method also brings attention to the Latin text from John 1:29 on the golden rays. The co-founders of Studio Waldemeyer, Moritz Waldemeyer and Nazanin Farhabod, aimed to keep the technology seamless for a better visitor experience. The basilica's construction started in 1882 and wrapped up this year.
