$34m project preserves historic palace

Paintings, cultural relics, frescos, scriptures and buildings at a world heritage site have been safeguarded for future generations thanks to a long-term restoration program.

The central government and the authorities in the Tibet autonomous region have made great efforts to renovate and preserve the Potala Palace, the site's managers said on Thursday.

The palace is one of only three UNESCO World Heritage sites in the region - the others are the Jokhang Temple and the Norbulingka Park.
