Generate a large stone castle built...

Generate a large stone castle built in the style of a 16th-century European fortress, with thick defensive walls, battlements, round corner towers, a central keep, and a fortified gatehouse with a drawbridge. The castle must have at least 40 separate rooms in total, including several underground rooms (a dungeon, a wine cellar, a crypt, and storage vaults) reached by stairways beneath the main structure. Every room, including the smallest one, must be larger than 5x5 blocks in floor size — no room should be 5x5 or smaller. Include all the rooms and facilities a fully functioning castle needs: a throne room, a great hall, a kitchen, a dining hall, an armory, guard barracks, stables, a library, a chapel, multiple bedrooms, storage rooms, and a treasury, arranged around a central courtyard
