Underground/Underwater Palace

This massive underwater and underground structure is magnificient. It took over a year to get to the stage it's at now, and I dug everything by hand. It has a glass pyramid on the roof used as a skylight. There is a secret entrance hidden in a sand dune. The ceiling is 18 blocks tall. There is a huge underwater window for great views of the ocean. This project has much more progress to go until it is complete. I have not yet decided what it will be when it's done.
