Painting restoration work on a prominent Tibetan monastery in northwest China's Gansu Province began on May 3, local authorities said Monday.

The restoration of paintings on timber in four of the halls at Labrang Monastery is expected to be completed by the end of 2017, according to Sonam Je, relic protection manager at the monastery.

This is the first time the paintings have been restored since the monastery was built, said Sonam Je.

Workers will repaint the damaged parts using original processes and materials.

The project, involving 16 Buddhist halls  at the monastery, is part of a wider 300-million-yuan (43 million US dollars) plan, which began in 2012, he said.

Labrang Monastery, built in 1709, has six Buddhist colleges and 48 Buddha halls. Located in Xiahe County in the Tibetan Autonomous Prefecture of Gannan, Gansu, the monastery is one of the six great monasteries of the Gelug Sect.

Sprawling across an area of more than 800,000 square meters, Labrang Monastery is famed for its architecture. It has been a national cultural protection site in 1982.
