Just a few World Wonders. Stonehenge, the Parthenon, Christ the Redeemer statue, Chichen Itza, Easter Island statues, the Hanging Gardens of Babylon, the Pyramid of Giza, the Lighthouse of Alexandria, and part of the Great Wall of China. See if you can find Atlantis, too.
I tried to get them as to-scale as I could while still keeping good detail. This is the first map I've set out to make and upload that I've finally finished; the others are more complex and involved but they'll get there, eventually.

After departing the Flying City of Skyhaven to investigate the appearance of the strange ice spikes, your airship crashes just outside some ancient ruins. Fortunately, there is a large town nearby where you can take refuge as you continue your expedition to uncover the origins of the mysterious ice spikes and hopefully stop their growth before they reach the city…

This map started off as just a fun world to play around with the new ice-spikes biome, and turned into an adventure map giving an explanation on both the origins of the weird new ice spikes biome (I’m not sure what the original inspiration for that biome was), and the history of the Endermen. It’s my first map with a storyline, so I hope it works out alright. Also, I've put a lot of hidden Easter Eggs in the map, so see if you can find them all (there's a list after you complete the storyline).

I created the map using Glimmar’s Steampunk Texture Pack, so it looks best using that, but feel free to use whatever texture pack you want.
