Site Preparation

Castles need a big flat area — aim for at least a 50×50 outline, which fits walls + 4 corner towers + a central keep without feeling endless. Three sites: hilltop (natural defense + view, most dramatic), peninsula (water on 3 sides, saves two walls), plains (easiest, beginner-friendly). Mark the 50×50 with stone bricks first, then plan the interior. The top-view below is a standard layout: rectangular curtain wall, 4 corner towers, main gate, 15×15 central keep.

Build order 1. Mark the 50×50 outline 2. Corner towers first (they anchor the wall lines) 3. Walls + battlements 4. Gatehouse + moat + bridge 5. Keep last (tallest = focal point)
Build the corner towers before the walls — they fix the wall lines and stop the footprint from drifting. The keep goes up last so you can judge its height against the finished walls.
Warning: Build the 4 corner towers before the walls — they anchor the lines so the footprint can't drift. Build the keep last so you can judge its height against the finished walls.

Wall Construction

Stone brick body, 6–8 tall, 2+ thick. Battlements on top (alternate blocks), iron bars inside to stop falls. Never one block type — here's the weathered mix:

Mossy stone brickAged, patchy face~25%
Cracked stone brickWorn, broken look~25%

Warning: The soul of medieval castles is weathering. Mix stone + mossy + cracked 1:1:1 — far better than pure stone, which looks like a new playground with no history.

Towers & Gatehouse

Corner towers, round or square, 5–7 diameter, 2–3 blocks taller than the wall (top floor = archer nest). Gate 3×3 or 4×4 with an iron-bar portcullis and carved-stone frame; a small guard tower on each side. Dig a 3-deep dry moat in front, cactus/spikes at the bottom as 'caltrops'.

Keep & Interior

The keep is the core: 15×15 base, 3–4 floors. Ground: great hall (long table + fireplace + armor stand), kitchen (4 furnaces + smoker). Second: lord's bedroom (double bed + enchanting + chests). Third: library (bookshelves + desk + lectern). Basement: dungeon (iron door + bars + campfire) and rows of chests. Dark oak slab triangular peak on top.
