Cavecraft was the name given to a Minecraft server created by Danno (DinocoDan). The server was created in order for Danno to create a massive underground cave which included an underground city.
The cave itself has been designed by Danno. The design includes a giant control room which has two floors and a staircase leading down through. The bottom of the cave has a lava pool with a hidden room in the lava.
The design also includes a bridge leading out of the control room into a even bigger cave which acts as the city. The design of the city included a tall tower in the center of the city which will act as the main tower and meeting area ect of Danno and his friends.
