In Genesis, the Ark’s opening near the top is called a window in many English translations.
Genesis 6:16 instructs Noah to make a window or opening for the Ark and to finish the structure to a specified height. English Bibles vary in how they translate the underlying Hebrew wording. Some say “window,” while others use “opening,” “light,” or related terms, reflecting differences in interpretation and translation tradition.
Genesis 8 later says that Noah opened the window of the Ark before sending out the raven and the dove. This connects the construction instruction with the later scene in which Noah observes conditions outside and releases birds.
The passage does not clearly describe a modern glazed window. Nor does it say that the opening was a fully enclosed cabin, observatory, or chimney. “A window” is the conventional short answer for the wording found in many English versions, while “opening” acknowledges the translation variation. The Ark’s door is mentioned separately in the same construction passage.
