Minas Morgul was a city/fortress of Mordor. Minas Morgul was once called Minas Ithil, the Tower of the Moon. It was the sister city of Minas Anor (later known as Minas Tirith) during the early part of the Third Age. Situated in an upland valley at the feet of the Mountains of Shadow, it commanded the only easily accessible pass through the mountains into Mordor and east of Osgiliath, near the pass of Cirith Ungol.
