The Bay of Rómenna was an inlet of Belegaer on the eastern side of Númenor that separated Orrostar to the north from Hyarrostar to the south. The bay had a narrow opening where it met the ocean, widened in the middle, and narrowed again at the mouth of the Firth of Rómenna. Within the bay was a small isle called Tol Uinen. Prince Aldarion frequently anchored the Eämbar off of this island and lived aboard this ship due to Tar-Meneldur's coolness to his son's nautical outlook.
