The Ivy Bush was an inn located on Bywater Road in the Shire. It was frequented by the Hobbits of Hobbiton, and Bywater. It was here that Gaffer Gamgee got quite an audience who were interested in the stories he told about Bilbo, and Frodo Baggins.
The Ivy Bush was also the name of a public house located on Hagley Road, Birmingham, England. When Tolkien lived on Stirling Road this would have been his local hostelry and could be found halfway between his house and the Birmingham Oratory, where he worshiped for a time.
