Japanese experts from the Monotsukuri University will help to survey and redraw the palace’s original structure, and supervise the restoration of decorative patterns on the palace.

The Long Duc Palace is a wooden structure built by King Gia Long of the Nguyen Dynasty in 1804, carrying the original architecture of Hue imperial palaces in the central province of Thua Thien-Hue.

Over the past 200 years, the building has been deteriorated.

The restoration project is part of a programme to conserve the entire Can Chanh Palace in the complex of the Imperial Enclosure, which was recognised as World Heritage Site in 1993.
