Create a short description of a gloomy scene outside town with a portcullis and a stone wall.

Large stone blocks stack atop one another to create a dull grey wall that surrounds the courtyard. A steel portcullis is raised, allowing access to and from the courtyard through an arched gateway. Large slabs of green slate pave the ground, covering nearly every square inch. Care has been put into maintaining the area as none of the slabs contain cracks or even pitting.
