Barad Eithel (also named Eithel Sirion) was the fortress and capital of the realm of Fingolfin and Fingon, while it endured. It was located in the mountainous eastern foothills of the Ered Wethrin, at the source of the River Sirion, just outside Hithlum, some sixty miles from Thangorodrim. It was attacked and besieged many times during the First Age by the forces of Morgoth. When Men came into the service of the Ñoldor, it was entrusted to the House of Hador. It survived the Dagor Bragollach but was conquered and occupied by the enemy after the Nirnaeth Arnoediad.
