The city is made up of many valuable ore blocks. There are walls on the outside along with gates. There are buildings inside along with a large pond in the middle, including the Palace, where Isa lives with her subjects.
Below the city's surface, there is a tunnel leading to the bottom of the island. There are chests with Spawn Eggs. It's also where Benedict lives.
The city was believed to be floating above The Void, as announced by Isa. However, it was revealed that it was floating above the Overworld.
The Sky City is a city floating in the sky. The exact location of the Sky City, however, is unknown (other than the fact that it is located high above the Overworld).
The Sky City is ruled by Isa (the Founder), and has very strict rules that prohibit its inhabitants from building without Isa's permission. It also limits crafting and smelting and gives out harsh punishments to people who waste its resources or throw them over the edge, mainly because it only has the Eversource as a source of food and resources. However, it was destroyed by The Blaze Rods in "Order Up!", when they used the Eversource's spawn eggs to spawn hostile mobs in the city. After that, the city was abandoned, and possibly torn apart by the mobs.

- It was originally believed there was nothing below Sky City except the Void, however, it was later discovered that there were several untouched biomes beneath it, and that the city was actually floating high above the Overworld.
- Sky City originally started a small cluster of islands with a tree, as according to Milo or Isa (determinant). The original tree and island are located behind Isa's palace, along with a crafting table, water body and a cobblestone generator.
- It was unknown how Isa, the Eversource, and the inhabitants of Sky City got onto the sky island to create it, as there was no way for them to get up there other than the Sky City Portal.
- They couldn't have started from the ground either, since at first they thought it was The Void but was revealed to be floating above the Overworld.
- Sky City is mentioned by PAMA when Petra and Lukas are chipped.
- PAMA mentions about the adventures they had and one of them he says, "A City in the Sky."
- Dropping any type of block (including dirt and cobblestone) is considered an "egregious waste of materials," or a felony.
- Sky City, especially the idea of its origins and the cobblestone generator, is a possible reference to "Sky Block", a popular Minecraft map.
