a thatched roof of poles

[flowersophy]

Hi,

What does "a thatched roof of poles" mean? I only know the meaning of "thatched roof".
It is nothing more than a deep pit, circled by the same pole-and-mud walls that the house is built of, a thatched roof of poles and bundles of grass tied down with stringy bark strips. There’s no door. You simply call out to make sure it’s unoccupied, and then enter around the curved privacy wall.
(Quoted from a novel Anthills, Elephants and Other Fascinations by Rina Flanagan)

Thanks very much!

If the author put it in your way, I would understand it better. Thanks very much, Glenfarclas!
