what were the names of the two towers
The Two Towers In letters to Rayner Unwin Tolkien considered naming the two as Orthanc and Barad-dûr, Minas Tirith and Barad-dûr, or Orthanc and the Tower of Cirith Ungol.[3][4] However, a month later he wrote a note published at the end of The Fellowship of the Ring and later drew a cover illustration, both of which identified the pair as Minas Morgul and Orthanc.[5][6] In the illustration, Orthanc is shown as a black tower, three-horned, with the sign of the White Hand beside it; Minas Morgul is a white tower, with a thin waning moon above it, in reference to its original name, Minas Ithil, the Tower of the Rising Moon. Between the two towers a Nazgûl flies.
