The Lost Cities Mod allows the player to play in an old abandoned city instead of the normal overworld. When you create your world you can select ‘Lost Cities’ as your worldtype. You spawn in an old and partially destroyed city that takes over the entire overworld.

This mod is very configurable. You will be able to add custom buildings and use modded building blocks. This mod can be used server-side only (so vanilla clients can connect).
Features:
- You can choose “Lost Cities” as your world type or access it as a separate dimension (default ID 111). This dimension can be entered by placing a bed on two diamond blocks surrounded by six skulls and attempting to sleep in it.
- The mod generates highways, bridges, tunnels, subway systems, dungeons, spawners, and loot throughout the city.
- Players can configure the mod to include custom buildings, blocks, and control how cities are generated. There are also presets called “profiles” to alter world generation.
