"Imagine an awe-inspiring brutalist cathedral reimagined for the modern era, blending monumental concrete forms with vast glass facades and sleek metallic details. The structure rises like a sculptural masterpiece, its towering spires and angular geometry subtly evoking the silhouette of a Christmas tree or a crystalline starburst. Within, vast open spaces are illuminated by cascading light from stained-glass-inspired windows, abstractly depicting winter hues and celestial themes. The exterior is adorned with subtle grooves and textures that catch the glow of strategically placed lighting, creating an interplay of shadows and highlights. Surround the cathedral with a serene urban setting, featuring minimalist water features and snowy reflective surfaces that amplify its presence. At twilight, the artificial lighting transforms the scene into a luminous beacon of celebration, its implicit holiday symbolism resonating without traditional ornamentation. The overall design should feel timeless and reverent, celebrating both the spirit of modern architecture and the subtle magic of the holiday season."
