In July 2019, architects Ronald Rael and Virginia San Fratello installed pink seesaws in the slots of the border wall between El Paso and Ciudad Juárez, allowing people on either side to play with each other despite the international boundary that kept them apart. “The wall became a literal fulcrum for US-Mexico relations,” Rael wrote. “Children and adults were connected in meaningful ways on both sides with the recognition that the actions that take place on one side have a direct consequence on the other side.” He’ll be speaking in Seattle about this project, his greater work with the border wall, and his latest book, Borderwall as Architecture. by Jas Keimig
