Architectural history has focused primarily on how architecture represents the traveling of cultures and technologies. Conventionally, it has conceptualized the built object or unbuilt project as (often statically) subsuming cultural forces and embodying “exchange” or “influence” from elsewhere. This session aims to critically unpack such methodological tropes. Rather than how architecture represents cultural encounter, this session brings together papers that examine more closely how exactly routes and forms of circulation mediate architectural production. We invite papers that focus on these theoretical and methodological problems by following specific “routes” of architectural circulation.
