A gatehouse is a fortified structure built over or next to a gateway. It's designed to control access to a castle, town, or other fortified area. Gatehouses often include defensive features such as arrow slits, machicolations, and drawbridges. They served as a primary line of defense, providing a secure entry point. Think of it as the guardhouse of a larger fortification. Gatehouses are like the welcoming committee with serious security measures.
