Tête Carrée

This guide to the Tête Carrée in Nice starts with the one-way trick built into its punched aluminum skin, letting the library staff inside see out while no one outside can see in. It follows sculptor Sacha Sosno's idea for a head that reveals only half of itself, and architect Yves Bayard's challenge of keeping people comfortable inside a hollow metal bust exposed to Riviera sun and salt wind. Notice how the metal itself changes character depending on the hour and the light.
