Build a huge circular fantasy fortress/citadel on a large island. Use a perfectly round outer wall with multiple layers of defensive walls. Place a massive central tower in the exact centre, surrounded by several smaller towers. Divide the interior into symmetrical wedge-shaped sections with roads radiating outward from the centre to the perimeter. Add large perimeter towers evenly spaced around the outer wall. Scale: approximately 600 blocks wide, with the central tower around 100 blocks tall and the outer walls around 30–40 blocks tall. Make the whole structure feel enormous, imposing and highly detailed.
