Build a whole castle: a keep with corner turrets, a great hall, a chapel, barracks and stables; curtain walls with a wall walk, stairs, round and square towers and a twin-towered gatehouse; siege engines — a trebuchet, a catapult, a ballista and a battering ram; and the life of the castle — a throne, a banquet table, an armour stand, a weapon rack, a tournament tent, training dummies and targets, braziers, banners, a fountain, hedges and a stone bridge over the moat.

Same scale, grid and material names as the Medieval Village, Enchanted Forest and Harbour Town kits, so they mix in one scene and recolour together.

Wall pieces join up: curtain walls, stairs, towers and the gatehouse share one wall line (2.0 m thick, wall walk at 5.6 m), and in the World Builder they snap end to end.

Conventions: 1 unit = 1 metre, Y-up, models face +Z (a wall's outer face), pivot at the centre of the footprint on the ground. Modular pieces are 2.0 m long.

Includes: GLB for every asset, plus the Blender source of each one.
