The History of Middle-earth
In J. R. R. Tolkien's fictional universe of Middle-earth, Isengard ([ˈaɪː.zɛn.ɡɑrd]), a translation of the Sindarin Angrenost, was a large fortress. Both names mean "Iron fortress" (cf. German Eisen and Old English isærn = iron), though Isengard has a second meaning of "West Guard".
In The History of Middle-earth, Tolkien states that Isengard was built in the Second Age around the tower of Orthanc by the Númenóreans in exile. Its location was at the north-western corner of Rohan, guarding the Fords of Isen from enemy incursions into Calenardhon together with the fortress of Aglarond to its south.
The river Angren (or Isen) began at Methedras behind Isengard, which also formed its northern wall. The other three sides were guarded by a large wall, known as the Ring of Isengard, which was only breached by the inflow of the river Angren at the north-east through a portcullis, and the gate of Isengard at the south, at both shores of the river.
