The following buildings can only be created by certain Decisions. They cannot be built in baronies that already have a special building. The Parliament will become inactive if the realm capital is moved.
The Hall of Heroes is a building chain created on a holy site via the Defenders of Dievas, Defenders of Rod or Defenders of Ukko decisions. Upgrading the Hall of Heroes costs 225 Gold and takes 16 months.
The Hall of Heroes can be built multiple times by swapping faiths and remains active for all Baltic, Slavic or Finnish Pagan faiths. The bonuses this building provide stack with eachother, resulting in a possible tripling of the above bonuses.
