You get it and it expires too quick. Why not just make the Citadel Building expire at Assembly line instead? Seeing how hard it is to get Siege Weapons the XP that +5 can really be a factor. Cause even if the defensive bonuses go away you can certainly use that +5. Ether make it available at construction or do what I said with assembly line.
Imagine how much that could improve the spanish civilization. Their Siege Weapons would be fierce!!
