A fictional kingdom of Men in J.R.R. Tolkien’s Middle-earth, Rohan plays a key role in The Lord of the Rings trilogy. A longtime ally of the kingdom of Gondor — the so-called greatest kingdom of Men during the Third Age — Rohan is known for its cavalry, the Rohirrim. In The Two Towers, the second book in the Lord of the Rings trilogy, members of the Fellowship spend time in Rohan, though it’s anything but majestic at first.
