Geometric Triangles in Seoul Train Terminal Skylight

Broad skylight floods the restored train terminal interior with soft, diffused midday illumination, highlighting a wall of interlocking triangular panels. The metallic surfaces reflect the overcast sky, creating a cool palette of grays and muted blues that matches the late autumn air visible through the glass. Gentle shadows fall across the sharp edges of the geometric arrangement, showing the precision of the modern architecture against the historic vaulted ceiling. Raindrops streak the upper windows, blurring the distant cityscape into a soft haze. One triangular panel catches a faint highlight where the light meets the cold metal edge.
