20. The Atlantis Sunken Monument Citadel

What This Idea Means

A breathtaking underwater mega-city enclosed in an enormous ocean-drained glass sphere, or fully submerged with glowing prismarine temples and aquatic life sanctuaries.

How to Make It

  1. Outer Enclosure: Drain a large area of ocean using sponges inside a giant 80-block glass sphere or multi-dome structure.
  2. Monument Architecture: Build classical Greek/Atlantean temples using quartz pillars, prismarine bricks, sea silk (white wool), and gold accents.
  3. Aquatic Landscaping: Fill surrounding exterior waters with sea pickles, coral reefs, conduits, and glowing kelp forests to frame the dry interior city.

Tips and Variations Needs

  • Conduit Power: Position multiple active Conduits around the city perimeter to give players permanent underwater breathing, night vision, and speed.
  • Variations: Build an Ancient Ruined Atlantis overrun by drowned mobs, sunken ships, and shattered glass domes filled with sea life.
