The production is also boosted by enthusiastic population and by boosts of certain great buildings. The building's coin production can be plundered if it isn't motivated. Players generally refer to this building as SoK.
This building requires a road connection.
The Shrine of Knowledge can be upgraded by Shrine of Knowledge Upgrade Kit item. To upgrade the Shrine of Knowledge, use the Shrine of Knowledge Upgrade item on the Shrine of Knowledge that is already situated in your city. Its upgraded version will then be placed directly on the same spot in your city and the production timer will not be reset. Note that the upgraded building will be from your current era, even if the old one was from one of the earlier ages.
The Upgrade can only be obtained from the Antiques Dealer.
