BEIJING, March 4 -- Mutianyu, a famous section of the Great Wall, now has a designated area for graffiti to better protect it after media reported that many foreign tourists left their words on the old buildings.

Mutianyu, one of the best-preserved parts of the Great Wall, is located in Huairou district, 70 km northeast of central Beijing.

This section of the Great Wall has frequently been the target of graffiti in English and other languages, according to a statement from the district's publicity department on Sunday.

In fact, more foreign languages appear than Chinese, a report published by Beijing Evening News said on Friday. The No 5 Fighting Tower building is a popular spot for leaving graffiti, with most of it in English, the report said.

For many foreign tourists, Mutianyu is their first choice for seeing the Great Wall in Beijing.

As a key national cultural relics site, Mutianyu attracts many tourists every year, with 40 percent from foreign countries, according to the publicity department.

For years, the administration office of Mutianyu had arranged routine patrol teams to discourage tourists from graffiti writing. Anti-graffiti placards were also added.

Meanwhile, the cultural relics protection department was ordered to restore the defaced buildings.

Yet graffiti has remained a problem in Mutianyu, administrators said.

To solve it, they established a free graffiti zone for tourists in the No 14 Fighting Tower building. "As many tourists like to carve words on buildings, we will develop the graffiti writing area as a new scenic spot of Mutianyu," said a director of the administration office.

The office said it plans to set up two more areas, in fighting towers No 5 and No 10 for tourists to carve or write their names in the future.

An electronic graffiti board is also being considered, it said.

The new policy gives visitors inclined to improperly leave their names an approved place to do so, which will better protect the ancient buildings of Mutianyu in the long run, said a publicity official, surnamed Wen, of Huairou district.

Xu Fan, a member of the panel of tourism experts of the World Tourism Organization, said that designating an area for graffiti was acceptable. But she questioned the plan to add more such areas and said an electric board for graffiti writing was a better choice.

Signage is also good, Xu said: "In current areas where tourists carve words spontaneously, the administrators should also set up signs to guide people to the newly established graffiti writing area."
