The Qianlong Garden in the northeastern section of the Forbidden City will receive a US$12 million face-lift by the Palace Museum, administrative organ of the Forbidden City, and the New York-based World Monuments Fund, according to an agreement signed in the palace yesterday by the two parties

Experts from the Palace Museum, the Washington-based Smithsonian Institute and a few other private US institutes will be involved in the project, Bonnie Burnham, president of the foundation, told China Daily.

The Qianlong Garden, which Emperor Qianlong (reign 1736-1795) built for his retirement in the early years of his reign, was completed in 1776 and cost 1.4 million taels of silver to construct (approximately RMB280 million today), according to Li Ji, executive deputy director of the Palace Museum.

It has remained virtually untouched since then. Meanwhile, other parts of the Forbidden City underwent continuous changes throughout the Qing Dynasty (1644-1911).

Besides the corridors, artificial hills and bridges placed artistically among the buildings, the Qianlong Garden is unique in terms of the interior décor of its buildings, according to Burnham.

The designers used the best traditional material and techniques, together with Tromp l'Oeil paintings and perspective techniques from the West, to create a rich and elegant imperial interior space, exemplifying the cultural differences between the East and the West.
