When studying Architectural History, the most important thing to remember is to study the social, economic, and cultural influences on it. Buildings being such public, interactive pieces cannot help but be deeply affected by culture – which is why we know so much from archaeological ruins that is not mentioned in records. The building and the public are intertwined. Everything – myths, defecation procedures, medical abilities, et cetera – will tell you more about the building and why than just studying the building in a vacuum.
Then why do Architecture students study only Architecture and a little Engineering and a little Art? Where's Landscape Architecture? Where's Interior Design? Where's Sociology? Politics? English? Film? Psychology? Save us Marcus Vitruvius Pollio! Where's Astronomy? Chemistry? Linguistics? Business? Economics? Archeology? Medicine? Music? Forestry? Biology? Fisheries? Law? Where is it all? This seperation does no good for the profession and is slowly dying. Economics and business catch-phrases like "streamlining," "efficiency," and "common sense" have finally begun to reunite the branches of architecture. Finally. Hopefully schools will realize this soon and let students take various classes without punishing them.
