A second joint restoration and on the job training scheme is now underway on the outskirts of Hué, at the mausoleum of Tu Duc, the fourth emperor of the Nguyen dynasty. The pilot project`s core aim is to conserve and restore the gateway and spirit screen at Tu Duc's actual tomb. Yet the German restorers and trainees – all of whom worked previously on the An Dinh project – are also compiling research data for a manual: recommendations on the future restoration of the entire Tu Duc site and similar architectural ensembles. Typical tropical problems crop up, as they did at the An Dinh Palace: frequent rain, extreme humidity and inadequate maintenance, here exacerbated by the inexorable jungle overgrowth and tourism. The project timeframe is March 2009–July 2010. Restoration here differs from previous practice in Vietnam: the traces of time are to remain legible, original artwork and complementary reintegration to remain distinguishable from one another. The structure is to retain its inimitable patina and beauty yet be safeguarded against further deterioration and thus preserved for future generations. It will be exemplary for the extensive site. An exhibition about the project will be presented as part of the Hué Cultural Festival in June 2010.
