Gatehouses are buildings or structures that contain an entranceway or gate. They may be located along a town or castle wall. Gatehouses may be fortified and contain a barracks for a town or castle guard. They may operate a drawbridge that spans a moat. They may be combined with a watchtower to observe travelers and potential enemies approaching by road or a bell tower to raise the alarm. Passing through a gatehouse may be restricted to only certain individuals or may require travel documents. Gatehouses are home to guards.
Gatehouses represent a gateway between locations and may be used by worldbuilders as portals between realms or other locations.
