Doriath

The mighty forest kingdom of Elu Thingol, greatest of the realms of the Sindar in Beleriand. The kingdom lay in two parts, separated by the River Esgalduin: the lesser, northwestern Forest of Neldoreth, and the greater, southern Forest of Region. These forests, and the small oakwood known as Nivrim on the western banks of the Sirion, were encompassed by the Girdle of Melian, which protected the land from its enemies.

In the midst of Doriath, carved into the rock beside the River Esgalduin, lay the Halls of MenegrothThingol, the Thousand Caves, citadel of King Thingol and Melian his queen.

Though Thingol ruled Doriath for long ages, he was slain in the last years of the First Age by Dwarves. After this his realm was ruled for a short time by his grandson Dior Eluchíl, before its final destruction by the Sons of Fëanor.
