Where did Kubla build the dome?

Kubla Khan, the Mongol emperor, famously built his grand palace and a dome in the city of Shangdu (Xanadu), located in present-day Inner Mongolia, China. The palace complex included a magnificent dome that symbolized his power and the grandeur of his empire. This site is often celebrated in literature, notably in Samuel Taylor Coleridge's poem "Kubla Khan," which evokes the lush and imaginative qualities of this legendary location.
