In Genesis, where was the Ark’s door located?

In Genesis, the Ark’s door was located in its side.

Genesis 6:16 describes the Ark’s design and says that Noah was to place an opening, or door, in the side of the vessel. The same verse mentions lower, second, and third decks, giving the Ark a vertically organized interior. The wording is a construction detail within the biblical description, not a modern shipbuilding specification.

Readers sometimes associate the Ark with a roof opening because Genesis later says Noah opened the window he had made. The window and the door are separate features in the narrative. The door is specified in the side, while the window is used during the waiting period after the rain and rising waters. Artistic reconstructions often change the proportions and placement of these features, so illustrations are not reliable evidence for the exact biblical wording.
