Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
‘Architecture’ may at first appear to be a more fixed and finite term. It has a threedimensional, tangible, useable form. But questions remain about what can be considered architecture and what cannot, and by this I mean that we usually understand architecture to incorporate aesthetic as well as functional consideration into its structure. Anything that does not fall into this category can be described as ‘just a building’. This may seem too simple. Can architecture be determined solely by the use of refined architectural style – high or polite architecture instead of vernacular?
Dana Arnold, Reading Architectural History (2002), Ch. 1 : Reading the past : What is architectural history?
The hasty multitude Admiring enter'd, and the work some praise, And some the architect: his hand was known In heaven by many a tower'd structure high, Where scepter'd angels held their residence, And sat as princes.
John Milton, Paradise Lost (1667; 1674), Book I, line 730.
