- Minas Tirith
- A tower on the island of Tol Sirion that guarded the Pass of Sirion. Minas Tirith was built early in the First Age by Finrod to keep watch upon the doings of Morgoth on the northern plain of Ard-galen and prevent passage south by Orcs through the Pass of Sirion, the West Gate of Beleriand. It was under the command of Finrod's brother Orodreth.
- In 457 First Age it was stormed and taken by Sauron. Sauron, then also known as Gorthaur, made it a place of such terror and horror it was renamed Tol-in-Gaurhoth, the Isle of Werewolves.
- Mount Dolmed
- A mountain in the Ered Luin that loomed over the only known pass from Eriador into Beleriand. It was here that according to Dwarves two of their Fathers, the founders of the Broadbeams and the Firebeards, awoke. Their descendants later established the Dwarven cities of Nogrod and Belegost. Nogrod was established near and under Mount Dolmed itself, Belegost lay more to the south.
- After the War of Wrath the Ered Luin were broken at the location of Mount Dolmed and an arm of the sea, the Gulf of Lune, broke through it. Mount Dolmed was completely destroyed together with Nogrod.
- Mount Rerir
- A peak of the Ered Luin in Thargelion to the north of Lake Helevorn and the sources of Greater Gelion. The land around the mountain belonged to Caranthir, who built a fortress on its western slopes. The fortress was destroyed during Dagor Bragollach and the Elves retreated to Amon Ereb.
