Hoi An owes its easygoing provincial demeanour and remarkably harmonious old-town character more to luck than planning. Had the Thu Bon River not silted up in the late 19th century – so ships could no longer access the town’s docks – Hoi An would doubtless be very different today. For a century, the city’s allure and importance dwindled until an abrupt rise in fortunes in the 1990s, when a tourism boom transformed the local economy. Today Hoi An is once again a cosmopolitan melting pot, one of the nation’s most wealthy towns, a culinary mecca and one of Vietnam’s most important tourism centres.
