Officials for the Chongquing Municipality's tourist bureau estimate it would cost about $67 million to convert the 150-foot-high cave, which has 47,000 square feet of space, for use as a tourist attraction, Xinua reported Tuesday The cave has a constant temperature of 64.4 degrees Fahrenheit.

The tourist bureau says the cave, nestled in lush mountains would be "an ideal place for conferences and leisure travel," Xinhua reported.

In 1939, the Kuomintang Party used the cave to develop planes but by 1949 it was abandoned.
