BEIJING, July 6 (Xinhua) -- China's Palace Museum will publicize a catalogue of all its collections of cultural relics, the museum's curator Shan Jixiang said Friday.

The museum had completed cataloguing all the relics in its archives in June after seven years of efforts, including about 53,000 paintings, 75,000 calligraphy works, 16,000 pieces of copperware and 10,000 sculptures.

The publication of these relics is to put the treasures under public supervision, said Shan, who believes the move will help better conserve the relics.

The Palace Museum, or the Forbidden city, located in the heart of Beijing, was built in 1420 and became a UNESCO World Heritage Site in 1987.

It was the home of the emperor and the highest center of power for about 500 years.

The museum attracts more than 14 million visitors annually.
