Build a Roman-style aqueduct in Minecraft using stone brick pier columns, round arches, and an open water channel deck to carry a stream across a valley. This intermediate house build works in Minecraft Java Edition and Bedrock Edition, version 1.20+ and above. Budget around 1 hour for construction — have all materials in your inventory before you begin.
The Intermediate rating reflects either multi-layered construction, a larger footprint that demands planning ahead, or simple redstone circuits. You should be comfortable with basic survival mechanics and resource gathering before starting. Budget extra time for iteration — not everything lines up perfectly the first try.

Total distinct materials: 5. Gather everything listed above before you start — mid-build supply runs break your momentum.
Find a valley or ravine at least 20 blocks wide. Check the highest point along the valley rim using F3, then add 3 to get your aqueduct deck Y coordinate — you want 3 blocks of clearance above all terrain. Extend the aqueduct 10 blocks beyond each valley edge onto solid ground to provide stable anchor points. Mark the two anchor ends with temporary blocks.
Aqueduct piers are spaced every 5 blocks along the crossing. Each pier is 2x2 stone bricks rising from the valley floor up to 2 blocks below the deck height. At the top block of each pier, add stone brick stair blocks on all 4 faces tapering the pier into the arch spring — this is the visual transition from column to arch.
Between each pair of piers, build a round arch spanning a 3-block-wide opening. The arch profile is: 2 blocks straight up from the pier top, then 1 block in and 1 up on each side, meeting a keystone slab at the peak center. Use stone brick stairs for the angled arch faces — 2 stairs facing each other flanking a center stone brick slab forms a convincing arch profile.
On top of all arches and spanning the full length, build a 3-block-wide stone brick deck. Raise side channel walls 2 blocks on both outer deck edges, forming a U-shaped water channel 1 block wide in the center. The deck must be perfectly level — use F3 to confirm the Y coordinate of every deck block matches before placing the channel walls.
Place water source blocks at the uphill end of the channel — the water will flow the full length and cascade off the far end. Cap the tops of both channel walls with cobblestone wall blocks as a decorative parapet rail. At each land anchor end, build a 3-block-wide stone brick approach ramp using stair blocks descending from deck height to ground level over 3-4 steps.
