The hospital is a building in The Conquerors 3. It replaces the Support Center in The Conquerors Mark II. This building slowly heals nearby units from your team, this is useful for healing major units such as Juggernauts after a fight. It is not recommended that you build more than 3 as it is excessive and you will probably focus on getting new units to aid in your army. You want to put this building far back as it can't take a lot of punishment and it has no defensive capabilities.
