Letters to the Mayor is an itinerant exhibition that displays letters written by architects to their city mayors. The project has been presented in Athens, Bogota, Buenos Aires, Lisbon, Madrid, Mariupol, Mexico, New York, Panama City, Sao Paulo, Taipei, and Taichung. Taking the form of an exhibition and a series of public debates between architects, the mayor, and citizens at large, Letters to the Mayor is a forum for the discussion of the future of cities and the built environment. The project provides a transversal understanding of relevant issues within local contexts, and shared concerns throughout cities around the world. Each edition of Letters to the Mayor invites one hundred local and global architects to deliver their thoughts directly to the desks of elected officials, and simultaneously into the public consciousness. For this occasion in Berlin we were invited to write a letter. The letters are on display until February 2, 2020.
