LHASA, Jan. 25 (Xinhua) -- A collection of 185 cultural relics from Tibet Autonomous Region will be exhibited at the Capital Museum in Beijing in late February.

The items on display come from 13 cultural relics protection sites, including the Jokhang Temple, Sakya, Shalu, and Mindroling monasteries, and many of them have never been seen by the public.

"This will be the largest, highest-level exhibition of Tibetan cultural relics in years," said Pasang Norbu from the Tibet Museum.

Five of the most precious antiques, including a gold mask and silk fabrics are from Tibet's Ngari Prefecture, date back to the Zhangzhung Kingdom (500 BC - 625 AD), Norbu added.

Staff involved in the exhibition have kept the complete list of antiques top secret. "Apart from heavy guard, our museum will control the temperature and humidity for each antique to ensure they don't suffer any minor damage after leaving Tibet," said Liu Cheng with the Capital Museum.

The exhibition featuring four aspects of Tibetan culture will run for a month.
