A collection of digitized images of buildings and cities drawn from across time and throughout the world and is maintained by the University of Washington Libraries.

SAH Archipedia is an authoritative online encyclopedia of the U.S. built environment organized by the Society of Architectural Historians and the University of Virginia Press. It contains histories, photographs, and maps for over 20,000 structures and places. These are mostly buildings, but as you explore SAH Archipedia you will also find landscapes, infrastructure, monuments, artwork, and more.

Photos, measured drawings and written histories of historic American buildings from the
Historic American Buildings Survey (HABS) and the Historic American Engineering Record (HAER). The collection documents achievements in architecture, engineering, and landscape design in the United States and its territories for more than 43,000 historic structures and sites from 1933 to date.

This collection contains over 29,000 images -- primarily of architectural subjects, including interiors and exteriors of homes, stores, offices, factories, historic buildings, and other structures. Subjects are concentrated chiefly in the northeastern United States, especially the New York City area, and Florida. Many of the photographs were commissioned by architects, designers, owners and architectural publications, and document important achievements in American 20th-century architecture and interior design.
