Great Square

From Tolkien Gateway
The Oath of Feanor by Antti Autio

The Great Square, was a square at the top of Túna, in Tirion, the great city of the Elves of Valinor, where the tree Galathilion stood under the Mindon Eldaliéva.[1] It was also the location where Fëanor threatened his half-brother Fingolfin in public,[2] and where later he gave his infamous Oath.[3]
