Day 10 (Prompting Only): Heritage Across East Asia explores the historical formation of UNESCO cultural heritage across a connected region. Faint modern borders leave room to read cultural connections across China including Macao, Japan, the Korean Peninsula, and Viet Nam. Taiwan appears as geographic context. The retained selection contains 87 Cultural properties and 590 in-scope official component/site records; Natural, Mixed, and tentative-list entries are excluded.
Colors represent the starting bound of a reviewed historical formation or principal construction phase, never the UNESCO inscription year. Six intervals run from before 1 CE through 1–599, 600–1199, 1200–1599, 1600–1799, and 1800 CE onward. Older phases are darker. Of the 87 properties, 75 have a reviewed phase and 12 remain gray as Unknown. Full date ranges and uncertainty notes are retained; each component inherits its property’s phase, without asserting an individual building’s exact age.
The unevenly spaced timeline filters recorded phase-start bounds, allowing distributions to be explored through time. It does not establish completion, occupation, or survival at the selected date. Unknown records stay gray. Locations use UNESCO’s published component coordinates without displacement; overlapping points remain separate records and can be selected in the interactive map.
