buildings, the villages around Hà N?i possess a rich body of cultural, architectural and craft heritage. Less than one hour from the capital are over 500 specialist craft villages, producing an array of religious or artistic objects, as well as food products, industrial goods, textiles, basketware and much more. Despite the trials and tribulations Vietnam has endured, these traditions have remained alive; today they consti­tute the basis of material, social and spiritual culture among the village communities of the Red River delta. The artisans themselves, and their local institutions, see cultural tourism as a way of further improving the fortunes of the craft village communities and bringing their heritage to wider attention. Until recently, few guides or tourists had forayed into these settle­ments, some of which are lost in the maze of routes and tracks that criss-cross the rice paddies of the Hà N?i hinterland. The history and skills they harbour have been inaccessible to all but a few specialists. Few of the villages are signposted, yet between them they are home to three quarters of the architectural, religious and craft heritage of the upper delta. This book, the fruit of several years' research by specialists working in northern Vietnam, comprises ten itineraries, blending potted histories, legends, descriptions of craft techniques, signposted walks and maps, designed to introduce travellers and lovers of Vietnamese culture to forty or so villages around Hà N?i. Many of us have seen their wares on sale in shops in and around the 36 streets of Hà N?i Old Quarter or in other cities in West. This book is about the true lives and enduring skills of the nameless artisans who made them. 517 $aDiscovering craft villages in Vietnam 606 $aAsian Studies 606 $aSociology & Anthropology 606 $aconcurrence 606 $avillage 606 $aindustrialisation 606 $aVietnam 606 $aactivité sectorielle 606 $asecteur informel 606 $adivision du travail 606 $apollution des eaux continentales 606 $asectorial activity 606 $acompetition 606 $adivision of work 606 $apollution 606 $ainformal sector 610 $aindustrialisation 610 $ainformal sector 610 $aVietnam 610 $adivision of work 610 $acompetition 610 $apollution 610 $avillage 610 $asectorial activity 615 4$aAsian Studies 615 4$aSociology & Anthropology 615 4$aconcurrence 615 4$avillage 615 4$aindustrialisation 615 4$aVietnam 615 4$aactivité sectorielle 615 4$asecteur informel 615 4$adivision du travail 615 4$apollution des eaux continentales 615 4$asectorial activity 615 4$acompetition 615 4$adivision of work 615 4$apollution 615 4$ainformal sector 700 $aFanchette$b Sylvie$0662073 701 $aStedman$b Nicholas$01328431 701 $aDigregorio$b Michael$01328432 701 $aFanchette$b Sylvie$0662073 801 0$bFR-FrMaCLE 906 $aBOOK 912 $a9910340853203321 996 $aDiscovering Craft Villages in Vietnam$93038560 997 $aUNINA
