In Genesis, what was the Ark’s single opening or door placed in?

In Genesis, the Ark’s door was placed in its side.

Genesis 6:16 gives Noah instructions for making a door in the side of the Ark. The same verse mentions a window and three levels, creating the brief architectural description that accompanies the vessel’s dimensions. Genesis 7:16 later says that Noah entered the Ark and that God shut him in.

The text does not specify whether the door was on the left or right side, how large it was, or what mechanism opened it. It also does not describe a stern gate, ramp, or multiple entrances. Those features may appear in paintings, films, models, and modern replicas, but they are not stated in Genesis.

The detail matters because the Ark is often pictured from the front or above, where its side entrance may be hard to notice. The biblical wording is precise about the door’s position while remaining general about its construction.
