Much of western architecture emphasizes repetition of simple motifs, straight lines and expansive, undecorated planes. A modern ubiquitous architectural form that emphasizes this characteristic is the skyscraperfirst developed in New York, London, and Chicago.

A notable feature of Western culture is its strong emphasis and focus on innovation and invention through science and technology, and its ability to generate new processes, materials and material artifacts with its roots dating back to the Ancient Greeks.
