T-Centralen

This guide to T-Centralen in Stockholm covers the Blue Line's 1975 opening, after years of blasting through Stockholm's granite bedrock, and artist Per Olof Ultvedt's answer to how to honor the workers who built it. It follows his decision to trace real construction workers' shadows onto the cavern walls rather than carve their names or paint an abstract mural. You'll see the blue and white silhouettes marching across the vault above the platforms.
