The Hall of Fame is a prize first issued during the 2014 FoE Soccer Cup Event. The Hall of Fame is a specialized building that produces guild Power on a daily basis depending on the player's age when the building was acquired. The guild power amount does not automatically increase with player's age. When the Hall of Fame is motivated, its production is doubled. The production is however never boosted by enthusiastic population or by boosts of certain great buildings. The building can be plundered if it isn't motivated.
When first introduced into the game, the building was contributing to both Guild Power and Guild Prestige. However, this was not intended, as the building was supposed to only contribute to Guild Power. This glitch was later fixed in a subsequent update (1.29) and all guilds lost any Guild Prestige gained through Hall of Fame. Additionally, the values of Guild Power being produced by Hall of Fame were reduced.
The 2020 FoE Soccer Cup Event added the possibility to upgrade this building.
The Hall of Fame can be upgraded by Hall of Fame Upgrade Kit item. To upgrade the Hall of Fame, use the Hall of Fame Upgrade item on the Hall of Fame 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.
