Henneth Annûn was the longest-lasting of all the refuges in Ithilien. Like all of the other hidden refuges of Gondor in Ithilien, Henneth Annûn was created by the Steward Túrin II circa TA 2901 in response to incursions of Orcs from Mordor. At the bottom of the window was a bowl full of sharp stone knives. There are two entrances into the cave system- one being the route through which Samwise Gamgee and Frodo were led, and the other being the window itself. The waterfall cascading over the cliff-face had originally run through the cave itself, but was altered to flow over one of the entrances this likeness to a window gave Henneth Annûn its name.
Henneth Annûn, also called the Window of the Sunset, or Window on the West, was a hidden refuge of the Rangers of Ithilien in the northern part of Ithilien along the Ephel Duath, the Mountains of Shadow.
