The minecraft rendering of the future NASA science complex based on the former World Trade Center complex in NYC. It's called the "World Technology Center" as it's a new NASA space research & rocket development center. It has the same twin towers of the old WTC. Its planned to be built in 2035.

An epic city map home to the President of Minecraft R. John Chryslar, who's built this amazing city on a 70 square mile Island in the middle of the Caribbean. It took 4 whole years to build. Its main focal point and the City's namesake is the World Trade Center Complex in Downtown area. WTC City is home to over 21,437 villager mobs [i'm serious, this map has thousands of villagers all over the place, but there's no lag] who live peacefully in this beautiful "zombie free city". WTC City is divided into many districts: Downtown WTC City, Midtown and Uptown area, Hadfield Industrial area (west of the city), J.S. Island, WTC Island national park, and the NASA District (home to lots of NASA facilities). Other areas include the O'Brien, Farr and Neal districts, located north of WTC city.
This city and map has a total of 1,000 kilomteters of minecart track and 70 kilometers of tunnels, along with hundreds of minecart trains carrying villagers. This city has a massive rocket factory and steel mill complexes and well as numerous skyscrapers, NASA buildings, beautiful houses and even a secret base under the National Park.

Its so complex and adventurous I highly recommend you play in this city with an included NASA Texture pack, and there's lots of adventurous minecart train services to pretty much every biome. The current calendar year in WTC City is 1984. The recommended texture pack is on this link https://www.minecraftworldmap.com/worlds/_reGY

Note: this map is primarily built and played in Minecraft 1.8 - 1.8.9. Newer versions may cause lag due to the large number of active mobs with extra resources. This city is 50.45% complete, as they're new NASA areas under renovations, and a new Intercity project is underway.
Also I'm gonna upgrade my version soon!

A Minecraft Replica of the International Space Station, scale 2:1 for extra accuracy and with command blocks for cool zero gravity effects to mobs, items and the player. This ISS map is very accurate to the actual space station in orbit, as pictures and blueprints were used as reference.

For version 1.10 and above. Note: for some modules facing vertical, there are command blocks inside the space station that when its button is pushed, you can float up into the upper modules for a few seconds (usually 10-20s). There's an associated texture pack for the real life space station systems sounds and equipment. You can get the texture pack here https://www.minecraftworldmap.com/worlds/_reGY
