An endless inland wall with one long curved building inside it.
Sao Paulo is a broad inland wall of apartment and office towers with very little open sky between them. The Copan Building is a long curved slab that reads as a smooth wave among the rectilinear blocks, while the Banespa Building adds a narrow historic tower and small cap. Cathedral domes and sharp church points can appear lower in the frame, but no single skyscraper dominates the way Taipei 101 or Burj Khalifa does. If the outline feels endless, dense, and layered from edge to edge, choose Sao Paulo. The curved Copan mass is the strongest landmark clue; the overall scale comes from the city's uninterrupted vertical carpet.
