Architectural phenomenology is a movement within architecture that began in the 1950s, reaching a wide audience in the late 1970s and 1980s, and continuing until today. Architectural phenomenology focuses on human experience, background, intention and historical reflection, interpretation as well as poetic and ethical considerations with authors such as Gaston Bachelard.[21] Islamic architecture began in the 7th century CE, incorporating architectural forms from the ancient Middle East and Byzantium, but also developing features to suit the religious and social needs of the society. Examples can be found throughout the Middle East, North Africa, Spain and the Indian Sub-continent.
