China’s Reed Flute Cave is also known as the ‘Palace of the Nat­ur­al Arts’, and that should tell you plen­ty about what to expect. Named after the reeds that grow out­side (which are used to make flutes, obvi­ous­ly), the Reed Flute Cave’s walls are pep­pered with inscrip­tions from cen­turies gone by – proof if proof were need­ed that peo­ple have been pay­ing atten­tion to this place for a long old time. The inte­ri­or of the cave is also lit up by mul­ti­coloured lights, giv­ing it a real oth­er­world­ly theme that adds weight to the nick­name.
