With four floors, the tower consists of one room on each floor that is connected by a spiral stone stairway built into the seven-foot thickness of the massive outer wall.
Each floor has a window that overlooks the Streamstown River that flows alongside the tower.
There is a small thatch cottage attached.

Yeats described the ground-floor chamber as "the pleasantest room I have yet seen, a great wide window opening over the river and a round arched door leading to the thatched hall".
He also admired the mural stair, symbolically declaring "This winding, gyring, spiring treadmill of a stair is my ancestral stair; That Goldsmith and the Dean, Berkeley and Burke have traveled there."

There is a tablet on the wall that commemorates Yeats' sojourn:
I, the poet William Yeats,
With old mill boards and sea-green slates,
And smithy work from the Gort forge,
Restored this tower for my wife George.

And may these characters remain
When all is ruin once again.
