CORRECT! From: Kubla Khan
Almost done, keep going! :)
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
So twice five miles of fertile ground
With walls and towers were girdled round:
And here were gardens bright with sinuous rills
Where blossomed many and incense-bearing tree;
And here were forests ancient as the hills,
Enfolding sunny spots of greenery.
-Samuel Taylor Coleridge
(Yes, this is only the beginning of it, the entire poem is quite long)
