Great Buildings are special buildings inspired by world history which can be built to provide powerful benefits to the player. Each Age offers two Great Buildings (with the exception of Arctic Future), each one with its own unique bonus, graphic, and space required to build. Unlike conventional buildings which require only coins/supplies, Great Buildings have additional requirements of goods and blueprints which must be collected before the Great Building can be constructed. Once the Great Building's requirements have been met and the foundation laid, it will be level 0 and must be "leveled" to level 1 before granting benefits to the player. For Great Buildings to gain levels, forge points must be placed into them. For each level gained, the inherent bonus of that Great Building increases as well as rewards paid to top donors. At level 10, the Great Building will no longer advance until a full set of blue prints are traded. Once this occurs, a single level will be unlocked; this must be done for each level past 10.

All Blueprints can be viewed in the inventory menu which is located at the bottom left orange "inventory" icon of the screen. This is also where you can build the Great buildings.

You can acquire the 9 blueprints in the following ways:

  1. Doing positive social interaction. For example, polish and motivate.
  2. Plunder buildings after attacking another player, but lower find rate than motivating/polishing.
  3. Rewards from certain quests or Guild Expedition
  4. Helping in construction of a great building of another player by donating forge points. The blueprints will be received when the building levels, if you finish in reward position. See here.
  5. Trading in 2 duplicate copies of blueprints you already posses. The new one will not be either of the traded copies, but may be a different duplicate.
  6. Purchase any specific blueprint with diamonds in construction screen.

The Great Building blueprint that is received from a building that was recently polished, motivated or plundered will be from the same age as that building.


To place the great building, you will first have to acquire the 9 separate blueprints and also the required goods of the building's age. However, the placed great building is level 0 and it does not give any bonus yet. See the next section. A GB must be connected by roads to provide benefits or to allow FP contributions.


The great building on level 0 is just a construction site and it won't build up itself. Players have to use an amount of forge points to upgrade it. Once the building reaches level 1, it is built and start to give out bonuses but still can be upgraded with increasing bonuses to a maximum of level 10. In Patch 1.29 (7 July 2014) maximum level of Great Buildings has been removed. Now players can trade in a complete blueprint set to unlock levels after 10. Forge points must still be added to achieve these new levels however.

Details of the cost of forge points on levels can be found in the topic of each building.

Players who have great buildings have a "castle" icon on the social menu

To help construct a Great Building, simply visit a city of one of your friends, neighbors or guild-mates in which a Great building construction is present, and click on the Great building. You may now donate Forge points, and also view which reward you will receive (if any) for your current donations. You may only contribute to another player's Great Building(s) after you have researched Architecture in the Iron Age.

When the current construction level is completed, the top five most generous donors (not counting the building's owner) will receive rewards:

  • Medals (based on level and age of the Great Building)
  • Forge point packages (based on level)
  • Blueprints (as outlined below):
