In Genesis, which part of Noah’s Ark had its door?

In Genesis, Noah’s Ark had its door in the side. Genesis 6:16 describes a door placed on the side of the vessel, alongside its roof and three decks.

The detail is part of the short construction specification given before the Flood. Genesis does not describe hinges, a steering system, a mast, or a conventional bow and stern. Its emphasis is on enclosure, capacity, waterproofing, and the means by which Noah and the animals enter.

The side door is often shown prominently in paintings and films because it gives viewers a clear visual entrance into the Ark. However, many artistic versions add architectural features not mentioned in the biblical text, including multiple doors, elaborate ramps, or rows of windows.

The passage also says the Ark was covered with pitch and divided into compartments. These features support the image of a sealed survival vessel. The location of the door is one of the few specific architectural details Genesis provides.
