According to Genesis, Noah made one window or opening in the Ark’s roof.
Genesis 6:16 includes an instruction commonly translated as making a window in or near the roof. English versions differ because the underlying Hebrew term and the verse’s architectural wording are not completely straightforward. Some translations describe a window, while others use an opening or skylight-like term.
The singular answer reflects the traditional reading of the passage, not a modern architectural survey of the Ark. Genesis later says Noah opened the window of the Ark before sending out the raven and dove, linking the construction detail with the bird episodes. The text does not specify the window’s exact dimensions, glazing, or mechanism. Readers also sometimes mistake this opening for the Ark’s door, which Genesis mentions separately when describing God shutting Noah inside.
