In the Genesis Flood account, the Ark’s only named opening besides its door is a window.
Genesis 6:16 instructs Noah to make a door in the side of the Ark and an opening near the top. Many English translations render this upper feature as a “window,” while some use terms such as “opening” or describe it as a roof opening. The verse also mentions the Ark’s three decks.
Genesis 8:6 later says that Noah opened the window he had made in the Ark and sent out the raven. This links the construction instruction with the later bird episode. The text does not provide a detailed architectural plan showing multiple windows, chimneys, balconies, or hatches.
The translation variation means “window” is the standard concise answer in English, while “opening” reflects a broader rendering of the Hebrew wording. The key distinction is that Genesis explicitly names the side door and a separate upper opening.
