High Quality Content by WIKIPEDIA articles! Architecture of the night or nocturnal architecture, also referred to as illuminated architecture and, particularly in German, light architecture, is architecture designed to maximize the effect of night lighting, which may include lights from within the building, lights on the facade or outlining elements of it, illuminated advertising, and floodlighting. With the rise of artificial lighting in the 19th and 20th centuries, architects were increasingly aware of it as an element to be integrated into design; deliberate use of it has been popular at various times, notably in the design of skyscrapers and other commercial buildings in the 1920s and 1930s, in the 1950s and 1960s, and in modern festive city architecture.
