Isengard was a stronghold guarding the Gap of Rohan at the southern end of the Misty Mountains. The impregnable Tower of Orthanc stood within the walls of Isengard. Isengard was originally an outpost of Gondor, but in the later part of the Third Age it was home to the Wizard Saruman. During the War of the Ring, Saruman was defeated and the walls of Isengard were torn down by the Ents, and the Tower of Orthanc was reclaimed by Gondor.
