The document provides instructions for designing a medieval castle, specifying that it must include all 5 elements from Part A (crenellations, wall walk, tower, ashlar, and great hall) and at least 5 elements from Part B (kitchen, armory, dungeon, oubliette, solar, finial, moat, portcullis, murder holes, arrow slit, postern gate, barbican, or drawbridge). It then lists and defines the basic elements that comprise a castle, separating them into the required Part A and optional Part B sections.
