Points of Interest are spots for settlements. You can't put a settlement outside a PoI, neither can you put multiple in one. A PoI will first begin giving values and other things, once it has been built. Value of a PoI ranges from 1 to 4.
POI which has the value of 1, dosen't have to be huge. Either just 1 detailed building or a few less detailed buildings are fine. Please try have these things match with the names.
But for values 2-4 you will have to build towns and cities.
Special Points of Interest[]
While normal PoI only gives values, then some special gives other things.
