SHANGHAI, March 30 (Xinhua) -- Life-size replicas of three caves from the world-renowned Dunhuang Mogao Grottoes in northwest China's Gansu Province will be exhibited at Shanghai Tower, China's tallest building.

The caves were created in three different historical periods: the Western Xia regime (1038-1227), Tang Dynasty (618-907), and Western Wei Dynasty (535-556).

"We chose the three most representative grottos to showcase China's ancient interactions with civilizations along the ancient Silk Road," said Mi Qiu, the exhibition planner.

Installation of the replicas has been completed and the exhibition will open on April 28.

Dunhuang Mogao Grottoes, also known as the Thousand Buddha Grottoes, are a 1,600-year-old UNESCO world heritage site. They are located at a cultural and religious crossroads area on the ancient Silk Road in Gansu.

Another 118 cultural relics will be part of the exhibition including a grade-one cultural relic: the bronze sculpture known as the "Flying Horse of Gansu."
