Gae Aulenti transformed forgotten buildings into cultural landmarks, proving that history and modernity can coexist without compromise. From her early days in Udine to her landmark conversion of the Gare d’Orsay into the Musée d’Orsay, she redefined adaptive reuse and shaped a global standard for restoring, rather than replacing, the past. Her work shows that innovation can honour memory, and that architecture can be both contemporary and timeless.
