Construction of two elevators on China's most preserved ancient wall in Xi'an, capital of Shaanxi province, has triggered public outcry, forcing operators to halt construction.[Photo/Xinhua]

However, the bureau has not given an approval to allow the project to go ahead.

The committee explained that the steel frame structure and scaffolding were erected as the committee is organizing a repair and reinforcement of the South Gate of the ancient city walls, while carrying out some preparation work for the elevator construction.

Many view modern structures such as elevators added to historical sites as eyesores with the potential to damage the relics during construction.

Dong Hua, a resident in Xi'an, said people do not mind climbing some stairs to visit the ancient wall, whose value lies in its sense of history.

Some Chinese media have said that the committee's elevator construction made a bad example by starting construction on a historical site without getting a permit from relic preservation authorities.

"Under the 'camouflage' of developing tourism, many historical relics have been damaged," said a commentary in the Henan Business Daily.

It suggested relic preservation and tourist development departments carry out public consultations and introduce democratic decision making in developing and preserving historical sites.
