A few cities are emerging as new arts centers—Milan, Mexico City, Cape Town, and Marrakech, Morocco. Driving the change in Marrakech is the re-opening of MACAAL, an independent not-for-profit museum. It will now feature a permanent exhibition of work from the Lazraq collection, built by a father and son, Alami and Othman Lazraq, who are among the foremost collectors of African art in the world. Art from the past century to the present day will dot the space. Think Moroccan modernist pioneers like Hassan Hajjaj and Malika Agueznay, plus Malian photographers, Madagascan painters, and more. —Elena Clavarino
