SAH Archipedia (Society of Architectural Historians, USA)
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. This cross-section of the country demonstrates the richness and diversity of architecture and building practice across many centuries, from mud brick to steel, from ancient cliff dwellings to contemporary office towers—a history that unfolds in individual building entries and thematic essays written by leading architectural historians who survey and explain styles and typologies, materials and techniques, and social and political contexts, from local to state to national levels.
