This is an interior of an ancient city looking out at the main entrance gate.  We know that the gate was a very important place where people met for busines transactions, legal matters and announcements.  At the entrance there would usually be a piazza or open court.  The gates usually were made of several doors that would serve as barriers durring war and house guards durring the day.  There are several cutouts showing people doing different things such as weaving, cooking on a taboon and sheep and goats on the bottom floor.
