Through the Gap of Rohan flowed the rivers Isen and Adorn, which formed the effective boundary of the Kingdom of Rohan. Rohan was formerly known as Calenardhon, and thus the Gap was then known as the Gap of Calenardhon. The triangle between the Isen and Adorn rivers and the White Mountains was a contested area between the Rohirrim and the Dunlendings.
During the War of the Ring, the Fellowship of the Ring chose not to travel through the gap because they had learned Saruman was in league with Sauron, and instead passed through Moria, much to the frustration of Boromir, who had proposed that turning back towards the gap would be the best option after witnessing Moria's destruction.
Appearances in adaptations Edit
The Gap of Rohan appears as a battleground in both The Lord of the Rings: The Battle for Middle-earth and The Lord of the Rings: The Battle for Middle-earth II. It is also represented in The Lord of the Rings Online, where it is the site of constant skirmishes between Dunlendings and the Rohirrim, who are trying to hold the Fords of Isen.
