Poptropolis

Poptropolis is the ancient capital of Poptropica that stays under the sea and rises up every 100 years to host the Poptropolis Games. Centuries of being submerged in the sea has made the buildings decayed and the statues broken up and or sunk into its soil. When you are at the Main Street area, you will see a live Poptropican that appears to be either a statue or an actual formal resident of the city.

History
The origins of Poptropolis is unknown, but it most likely may have been the birthplace of all eight tribes of Poptropica. As of January 24th 2013,the island has sunk back into the sea. It still has a place on the map though, meaning it might be returning. There have been many hints that Poptropilis will return, but for now it remains in the sea.

Archictecture
The city has a Greek-Roman type of archictecture, similar to Mythology Island. It is also apparent based on some of the ancient clothes that some organizers of the games wear. Ancient Poptropolis resident's were probably brilliant architects, made known by the huge statues that decorate the Poptropolis Games courses.
