What is the name of a stately pleasure-dome in verse?

"Kubla Khan" by Samuel Taylor Coleridge

In Xanadu did Kubla Khan

A stately pleasure-dome decree:

Where Alph, the sacred river, ran

Through caverns measureless to man

Down to a sunless sea.

-----------------------------------

The name of the pleasure-dome is not mentioned. Kublai Khan [1214-94] was the great khan of the Mongols, and later the Emperor of China. He was the grandson of Ghengis Khan. The poem is said to have been written by Coleridge when he was on an opium 'trip', and later he said he couldn't finish it because he was interrupted 'by a gentleman from Porlock' [a town in Cornwall] and couldn't remember later how he had intended to continue.
