As Getai, in Sarmiszegethusa I recently had:
Getic Allied Tribe (level 2 government) - +1 experience
Sacred Mountain - +1 experience, +1 morale
Field of Games - +1 experience
Stone Temple of Ares - +1 experience, +2 morale

I was pumping out falxmen with silver chevrons (+4 experience) and +3 morale. Even if the morale bit didn't work, it's hard to argue with that!
