This thesis is related with the concept of monument lighting. It focuses on the interaction between two elements of art; light and the monument, and also the interaction between human and monument regarding the psychological, physical, and sociological factors. The study concentrates on the approach to the problem and discusses the facts that lighting designers and sculptors have to be concerned about in bridging the gap between public and monuments. Rather than expressing general lighting criteria, discussions are carried upon the examples to suggest a better understanding to the topic. The recommendations involve the case studies of two monuments and the evaluation of observer responses among different lighting schemes.
