|Etymology||S. ar "royal" + menel "heaven" + os "fortress"|
|Events||Downfall of Númenor|
It was founded as far back as the end of the First Age, when the Edain first migrated to the island. Conceivably Arandor was the first district they settled after landing in a firth that later led to the haven of Rómenna.
Armenelos contained the royal palace, the King's House, reportedly built with the help of the Maiar. Its finishing, together with the coronation of Elros in S.A. 32 marked the beginning of the Númenorean realm.
Armenlos means "Royal Heaven-fortress", from the Quenya elements ar, "royal", menel, "heaven", and os "fortress". At early stages of writing, this city was called by an Adûnaic name, Ar-Minalêth. It is uncertain whether this name was deleted or not.
