Mount Dolmed was a mountain in the Ered Luin or "Blue Mountains".
Mount Dolmed loomed over the only known pass from Eriador into Beleriand. It was here that according to the Dwarves two of the Fathers of the Dwarves, the founders of the Broadbeams and the Firebeards, awoke. Their descendants later established the Dwarven cities of Nogrod and Belegost. The two cities were established on the Eastern side of the mountain. Just a little of North-east of Dolmed was (Belegost), and a little to the South-east was (Nogrod).
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 and much of Belegost.
