The Century of Cities welcomes the visionary Gabriella Gómez-Mont, founder of Experimentalista and former Chief Creative Officer of Mexico City, to reflect on Mexico City’s staggering reinvention, from its sprawling challenges of the 80s to its current role as a global hub for urban innovation. Gabriella shares powerful stories of how Latin America’s early urban struggles became a catalyst for groundbreaking solutions, including Bogotá’s care blocks, Medellín’s urban cooling initiatives, and Mexico City’s bike revolutions. She introduces a bold vision for a League of Cities for the Imagination, where mayors and citizens transcend boundaries to reimagine our shared futures. From radical care policies to progressive feminist movements, Gabriella leaves us with a hopeful provocation: Cities, like dreams, hold our deepest fears and desires. By asking the right questions today, we may find the answers that unlock the possibilities of tomorrow.
