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 No Age, Arctic Future, and Oceanic Future ages having three Great Buildings each and Space Age Asteroid Belt having one Great Building), each one with its own unique bonus, graphic and space required to build.
Unlike conventional buildings which require only coins / supplies, Great Buildings have requirements of goods and a full set of 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 at level 0 and must be "levelled" 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 the rewards paid to the top 5 donors. At level 10, the Great Building will no longer be able to advance until a full set of blueprints are "spent" to unlock the next level. Once this is done, a single additional level will be unlocked. A full set of blueprints is required for each level after level 10.

You can acquire the 9 blueprints in the following ways:
- Aiding other players by polishing and motivating.
- Plundering buildings after attacking another player. This has a lower blueprint rate than motivating / polishing.
- Receiving rewards from certain quests, Guild Expeditions, Daily Challenges and Incidents.
- 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.
- Trading in 2 duplicate copies of blueprints you already possess. The new one will not be either of the traded copies, but may be a different duplicate.
- Purchasing any specific blueprint with diamonds in the construction screen assuming you already have at least 1 blueprint for that Great Building.
- Building the Rain Forest Project increases the chance of getting a blueprint by polishing / motivating.
- Buying them from the Antiques Dealer
- Certain Special Buildings, like the Shrine of Inspiration and the Altar of Hestia provides a random blueprint upon collection.
- Winning them in events.
Note: 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 Great Building must be connected by roads to provide benefits or to allow Forge Point contributions.
The Great Building at level 0 is just a construction site and it won't build itself like other buildings. Players must use Forge Points to upgrade it. Once the building reaches level 1, it is built and starts 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), the 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 be added to achieve each of these new levels.
Details of the cost of Forge Points on levels can be found on the page of each building.
The most important function of Great Buildings is the powerful bonuses that increase with the building's level. Depending on the building, you will get the following:
Gives an increased chance of gaining blueprints while aiding.
An amount of coins every 24 hours.
Chance to double collect the first number of buildings collected.
Chance to kill one enemy unit at the start of battles (for two-wave battles, the chance applies only to the first wave).
An amount of Forge Points every 24 hours.
Permanent happiness bonus.
An amount of medals every 24 hours.
Permanent population bonus.
Provides an amount of supplies every 24 hours.
Details of the bonuses of each Great Building can be found in the topic of each building.
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. However, keep in mind that if you level up another person's Great Building, it might cause them to lose their daily collection (if the building provides any). Good donation etiquette mandates that the last few forge points must be left for the owner to put.
When the current construction level is completed, the top four or 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):

As Great Buildings cannot be stored, the only way to remove them from the city grid is to delete/sell them. The Player will not receive any compensation for deleting the Great Building - neither goods nor blueprints nor invested forge points nor diamonds will be paid back. Also, all current contributions to an unfinished level will be lost for the respective contributors. When you want to build the GB again in the future, you will start from Level 0 and you will need a full set of BP again.
When selecting a Great Building for deletion, the player will be prompted with a dialogue in which he has to confirm his wish to sell the Great Building by moving a slider all the way from the right to the left.
