In Genesis, the Ark’s only explicitly named opening besides its door is a window.
Genesis 6:16 instructs Noah to make a “window” or “opening” for the ark and to finish it to a specified measurement. The Hebrew term and the exact construction are debated, so English translations differ: some say “window,” while others use “opening,” “roof,” or related wording. Genesis also mentions a door in the side of the vessel.
Later in the story, Noah sends out a raven and then a dove through or from the ark to assess the condition of the earth. The text does not provide a modern architectural diagram showing precisely how those birds were released. Consequently, illustrations often add details that Genesis itself does not state.
The answer should be kept distinct from the ark’s roof. Some translations interpret the Hebrew instruction as involving a roof-like structure, but “window” is the familiar answer in many English versions and is the term most directly associated with the passage.
