How many decks did God instruct Noah to build inside the Ark?

God instructed Noah to build three decks inside the Ark.

Genesis 6:16 describes the ark as having lower, second, and third decks. The verse appears in the instructions given to Noah before the Flood, alongside details about the vessel’s dimensions, window, door, and construction material.

These three levels are often understood as providing separate areas for Noah’s family, animals, supplies, and other necessities. The biblical text does not provide a modern architectural floor plan, so the exact arrangement of rooms and enclosures remains unknown.

Modern replicas of the ark frequently divide their interiors into three major levels to follow the Genesis description. This detail is sometimes omitted in children’s illustrations, which typically show a single open space filled with animals.
