Door of Night
From Tolkien Gateway
The Door of Night was a portal in the distant Uttermost West that leads to heaven, and/or the Void.
Eärendil's ship Vingilot was taken by the Valar from the rim of the world, passed through the Door and was lifted into the "oceans of heaven".
Later, Morgoth was cast through it after his defeat in the War of Wrath, but he ended up beyond the Walls of the World into the Timeless Void.
Other versions of the legendarium
In The Book of Lost Tales the door is mentioned to have been made by the Valar as a passage for the Sun, which would return into the World through the Gates of Morning in the east.
In the Ambarkanta, it was made expressly as a gateway through which to expel Morgoth.
