Hobbit-hole
From Wikipedia, the free encyclopedia
Hobbit-holes in J.R.R. Tolkien's Middle-earth universe were the original places where Hobbits dwelt underground. They were found in hillsides, downs and banks. By the late Third Age, they were replaced by brick and wood houses, however, some older style Hobbit-holes are still in use by more established Shirefolk, such as Bag End and Great Smials. Like all Hobbit architecture, they are notable for their round doors and windows, a feature more practical to tunnel dwelling that the hobbits retained in their later structures.
"In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat: it was a hobbit-hole, and that means comfort." --Tolkien(The Hobbit)
