The Last Homely House is a home in Imladris, from Tolkien's The Hobbit and The Lord of the Rings. Nestled in the mountains, nearly impossible to find unless you know where to look, Imladris is a beautiful haven where elves reside. Music, singing, and storytelling abound, and the peaceful atmosphere is a welcome refuge for a weary soul.
