Crown of Gondor
From Tolkien Gateway
The tall jewelled and winged helm that served the Kings of Gondor as a Crown. Tolkien described it in his letters as similar to the crown of the Pharoahs of Egypt. After the loss of the last King, Eärnur, it was held in the Houses of the Dead for nearly a thousand years, until a rightful heir (Elessar Telcontar) came forward at the end of the Third Age.
