In Genesis, what feature did Noah’s Ark have in its roof?

In Genesis, Noah’s Ark had a window in its roof.

Genesis 6:16 instructs Noah to make a window for the ark and finish it to a specified measurement. English translations differ in how they describe this feature. Some say “a window,” while others use terms such as “opening” or “roof,” because the underlying Hebrew wording is difficult to interpret precisely.

The passage also mentions a door in the side of the ark and three levels inside it. These details distinguish the biblical description from many artistic versions, which often add numerous windows, masts, sails, or decorative structures that the text does not mention.

The window becomes important later in the story. After the floodwaters had receded, Noah opened it before sending out the raven and the doves. Thus, it was not merely an architectural detail; it provided a way to observe conditions outside the vessel.
