As　the　carrier　of　history　and　culture,　cultural　heritage　has　outstanding　value　and　is　increasingly　vulnerable　to　natural　hazards　and　anthropogenic　changes.　The　research　on　the　risk　of　cultural　heritage　sites　around　the　world　is　becoming　more　and　more　mature,　but　the　research　on　Chinese　cultural　heritage　sites　is　inadequate.　The　purpose　of　this　study　is　to　fill　the　gap　in　the　research　on　multi-disaster　risk　assessment　of　cultural　heritage　sites　in　China　and　to　propose　an　integrated　approach　to　risk　assessment　based　on　Remote　Sensing　(RS)　and　Geographic　Information　System　(GIS)　for　the　protection　and　development　of　cultural　heritage.　This　study　identified　six　threats　to　cultural　heritage　sites:　landslides,　floods,　erosion,　urban　sprawl,　fires,　and　modern　road　networks.　Taking　Fortified　Manors　of　Yongtai,　Fujian　Province,　China　as　the　research　object,　this　study　collected　historical　satellite　images,　relevant　remote　sensing,　and　thematic　data,　used　GIS　technology　to　establish　a　basic　spatial　database,　and　constructed　a　risk　assessment　system　in　the　study　area　using　the　Analytic　Hierarchy　Process　(AHP)　and　the　Certainty　Factor　(CF)　model.　The　risk　of　Fortified　Manors　of　Yongtai　was　divided　into　five　levels:　extremely　low　risk,　low　risk,　medium　risk,　high　risk,　and　extremely　high　risk.　It　is　found　that　most　of　the　Fortified　Manors　are　in　high　risk　or　above,　accounting　for　69.28%,　indicating　that　most　of　them　are　in　a　very　dangerous　environment,　and　it　is　urgent　to　take　measures　to　monitor　and　protect　them.　©　2023　Elsevier　Ltd
