1. Improved Holding Sprawl
   
   • Level 1 Holdings w/ no buildings have no Sprawl
     
   • Upgradig your holding (castle, city, temple) will upgrade the main building and the Sprawl
     
     • There are four levels of sprawl that surround the holding that correspond to the holding level
       
     • The walls upgrade one level behind the holding
       
       • This means that a Castle 1 will have tribal walls
         
       • A Castle 2 will have Level 1 walls
         
       • A Castle 3 will have Level 2 walls
         
       • A Castle 4 will have Level 3 walls
         
     • You can bypass this by building fortification buildings (curtian walls, hill forts, raparts, or watch towers)
       
       • A Level 1 Castle with a Level 1 or Level 2 fortification building will get Level 1 Walls
         
       • A Level 2 Castle with a Level 3 or Level 4 fortification building will get Level 2 Walls
         
       • A Level 3 Castle with a Level 5 or Level 6 fortification building will get Level 3 Walls
         
       • A Level 4 Castle with a Level 7 or Level 8 fortification building will get Level 4 Walls
         
     • Cultures have Custom Castle, Wall, and Sprawl Graphics
       
       • Celtic, Norse, Western, Mediterranean, MENA, Indian, and Slavic
         
       • Burma has custom Castles, Cities, and Temples
         
       • Sami have custom Tribal Graphics
         
   • Game Rule to control whether Sprawl is shown in your game
2. Once you build a Burge or Higher (Castle or City Level 5, 6, or 7) the Walls and Sprawl are replaced with Custom Walled City Holding Graphics
   
   • Celtic, Western, Mediterranean, MENA, Indian, and Slavic
     
   • Game Rule to control whether custom Burge Holding Graphics are shown
3. Historical Burges
   
   • 867 Start Date: 28 Holdings across the map start as Burges
     
   • 1066 Start Date: 11 Additional holdings start as Burges
     
   • Custom Holding Graphics for many cities, including Rome, Constantinople, Marakesh, and others
     
     • Custom Holding Graphics include unique buildings represented on the map
       
   • Game Rule to control whether Historical Burges exist in your game
     
   • One-time decision shown when you add the mod to an existing save to add Historical Burges to your existing save
4. Rebuild Ancient Cities
   
   • Carthage: rebuild the City State following a unique Decision/Event Chain available to the ruler of Tunis
     
   • Knossos: rebuild the Capitol of the Minoans following a unique Decision/Event Chain available to the ruler of Iraklio in Krete
     
   • Each city has a fully custom Burge Holding Graphic including ancient unique buildings that appear on the map
     
   • You can decide not to persue the decisions, which gives a small amount of piety or prestige
5. Many new unique buildings all over the map

There was an issue with upgrading unique buildings added by the mod. This has been fixed.
