Reed Flute Cave in Guangxi autonomous region in China is a famous landmark, also known as the Palace of Natural Art. Natural limestone caves filled with wonderful and bizarre formations like icicles and rock formations with the additional effect of coloured light.
This geological object was named in honour of the cane, which is found outside the cave and used for making musical flutes. Its length is about 240 m and a vast territory, which is an impressive landscape. The object is ancient, since its walls are preserved inscriptions from the reign of the Tang dynasty, dated 792 BC
