the gates of morning

[the witch king]

Greetings all im not sure if this is a stupid question that i should know but where where the gates of morning that the men of numenor saild to and what was there?

[Beren87]

The Gates of Mourning were in the eaternmost portion of Arda. They were probably the gates in the Wall of Night, which the sun passed through in the morning.

[Inderjit Sanghera]

There is a picture of them on History of Middle Earth Part 2, with Earendil sailing ,into the 'void' (solar system) where Melkor and probably Sauron are lurking somewhere.
