Xanadu

Xanadu (Shangdu (上都))? was the name of the summer capital of Kublai Khan (1215-1294), a Mongolian leader who conquered much of Asia. Visited by Venetian explorer Marco Polo in 1275, it became fabled as a metaphor for opulence.

Xanadu is remembered today partly thanks to the poem Kubla Khan by Samuel Taylor Coleridge, which contains the often-quoted line "In Xanadu did Kubla Kahn, a stately pleasure-dome decree."
