Temples
Temples are the gateway to spiritual enlightenment for your peasants. The more spiritually enlightened they are, the happier they are and the more popular you are. The amount of spirit generated is based on what proportion of your housing and work buildings (i.e. buildings that require a worker) are within the radius of a temple.
If all your buildings are within the radius of a temple, then all your peasants are spiritually enlightened and you will receive the maximum popularity bonus.
Connecting Roads to Temples
If you connect a road between your keep and a temple, the temple's spiritual radius will expand, allowing more buildings to be covered.
