Architecture (Latin architectura, from the Greek ἀρχιτέκτων arkhitekton “architect”, from ἀρχι- “chief” and τέκτων “creator”) is both the process and the product of planning, designing, and constructing buildings or other structures.[3] 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.[4]
