In December 2019, Michael Falser, of the University of Heidelberg, a specialist on heritage preservation and the art and architectural history of South and Southeast Asia, published his two-volume study, Angkor Wat: A transcultural history of heritages, which he had spent almost ten years researching. The volumes cover the history of research of the most famous monument in Cambodia, Angkor Wat, the world's largest religious monument, listed by UNESCO as a World Heritage Site in 1992. The two volumes include more than 1,400 black-and-white and colour illustrations, including historical photographs and the author's own photographs, architectural plans and samples of tourist brochures and media clips about Angkor Wat, which has been represented as a national and international icon for almost 150 years, since the 1860s.
