Icons at the Turn of the Century

A comparison of buildings in Sydney, Bilbao, Dubai, and beyond that became images of their cities.

Burj Khalifa and Willis Tower show how structural strategies such as setbacks and bundled tubes determine a skyline. Plan, core, and wind matter as much as height.

This guide does not rank buildings by fame. It asks what allows one building to summarize a city in a single image.
