In the Book of Genesis, Noah is said to have built Noah's Ark.
Genesis presents Noah as a righteous man chosen by God to survive a catastrophic flood. He receives detailed instructions for constructing the vessel, bringing aboard his family, and preserving representatives of animal life.
The story identifies Noah as the builder, but it does not describe him as working entirely alone. His wife, three sons, and their wives enter the ark with him, although Genesis does not specifically state which people helped with construction.
Noah's Ark belongs to the wider ancient flood-story tradition. Related accounts appear in Mesopotamian literature, including the Epic of Gilgamesh, but those stories use different names and details. In the biblical account, Noah is the central human figure connected with the ark's construction and survival.
