What This Idea Means: Built entirely beneath the ocean surface, this trading hall offers panoramic underwater views of coral reefs, marine life, and ancient ocean ruins, housed within crystal clear glass domes.
How to Make It: Drain a 25-radius circular area beneath the sea using sponges. Construct double-layered glass domes or long glass tubes using Cyan Tinted Glass and Prismarine Bricks. Decorate surrounding water with sea lanterns, kelp, and sea pickles.
Tips and Variations: Incorporate conduit structures in the central hub to provide underwater visibility buffs and continuous aqua lighting effects throughout the complex.
