ThaMango's 24 Hour City

One of the largest Minecraft cities, all built in just 3 days - by over 60 builders! This huge city has everything you could want it to include, with iconic restaurant brands, a waterpark, themepark, resort island, a mall, a museum, hundreds of houses, a train system, a cable car and even an Ikea!
 
This giant city is split across multiple islands, even including numerous millionaire islands with private mansions. It's over 5000 x 5000 blocks in size.
