In Genesis, which part of the Ark was Noah told to make as its entrance?

In Genesis, Noah was told to make a door in the side of the Ark.

Genesis 6:16 lists several features of the ark’s design and says that Noah should make a door in its side. The same verse describes an upper, second, and third deck, giving the vessel a structured interior rather than a single open container.

The door is a specific architectural detail in the biblical text. It is not described as being in the bow, stern, roof, or top deck. Later paintings, models, and films often choose different visual arrangements, but those artistic choices do not change the wording of Genesis.

Genesis also says that the ark was divided into compartments and coated with pitch inside and outside. Together, these details present the ark as a large sealed vessel designed for flotation and containment, though the narrative does not provide a modern engineering blueprint.
