Barrow

A Barrow is a mound of dirt over a grave. Barrows in Middle-earth included those on the Barrow-downs and the ones before the gates of Edoras, where the kings of Rohan are buried. Frodo Baggins, Meriadoc Brandybuck, Peregrin Took, and Sam Gamgee all wind up in a barrow after their capture by a Barrow-wight in the Barrow-downs. The barrow is illuminated by a pale greenish light and many treasures are piled in the passage where the four hobbits are held. Frodo can hear from as if from far away the Wight's Chant as he looks around the barrow. Merry, Pippin, and Sam sleep, or are enchanted, throughout their time in the barrow and so don't see Frodo use a sword to cut off the Barrow-wight's hand when it comes after them. Once Frodo summons Tom Bombadil, Tom opens low door in the barrow and expels the Barrow-wight. He and Frodo carry the other hobbits out of the barrow and Tom Bombadil brings a load of treasure out of the barrow to break the spell of the barrow and keep other wights away from it. The four hobbits get their Barrow-blades from the barrow, which is said to be the grave of the last prince of Cardolan.
