The document discusses identifying Outstanding Universal Value (OUV) in historic urban landscapes. It explains that OUV is determined by examining the layered cultural and natural values of a place over time. The Historic Urban Landscape approach recognizes multiple interconnected tangible and intangible values, from archaeological remains to social practices. Mapping exercises and stakeholder consultations can help identify which values convey OUV and must be protected. Two examples - Bordeaux and the Solovetsky Islands - demonstrate how examining layers of history, culture, nature and integrity convey each place's unique OUV.
