Minecraft wiki entry for Building_a_metropolis, associated text: Hospital A place to care for injured players. Make a big house with a red cross on it, and fill it with beds, healing potions, surgery rooms, and so on. Hire "doctors" and get them to wear nurse and surgeon skins. You can even sleep in one of the beds there, and you will wake up peacefully after a bad episode. This will likely be the most visited building in your city and therefore you may want to hire security to take care of griefers and troublemakers.
