How can we transform urban environments to encourage durability and mediate the social price of myriad risks and vulnerability? Our work here is to build a bridge from archaeology to mainstream architectural and design theory. The study of places, landscapes, and regions links the two fields. Architecture can be shaped and enhanced by the long-term cultural and geographic perspective afforded by archaeology; architecture can offer archaeology a ride into the future. The bridge unites three domains: material, social, and aesthetic. We look to the past to find material technologies—new engineering and conceptual solutions to an array of problems—and the past obliges with many examples.Landscape Architectur
