The American Museum of Natural History broke ground June 12 on its Richard Gilder Center for Science, Education and Innovation. The $383-million, 230,000-sq-ft project will add galleries, classrooms, an immersive theater and a redesigned library. New York Mayor Bill de Blasio said at the ceremony: “Science is under attack. I hope young people will become devoted to protecting” the planet, inspired by the museum’s addition. “Our design for the Gilder Center will invite visitors to explore the wonders of the museum with its openness and smooth, flowing geometry,” said architect Jeanne Gang, founding principal of Chicago firm Studio Gang, adding that the project “utilizes the fluidity of concrete to create a porous structure and iconic interior.”
