I would say castles have to become obsolete with Artillery (a modification I added)--during the Renaissance and early industrial revolution days castles were different--the "star forts". These babies had a different design: no blindspots, low and thick walls, lots of earthworks and systems of ditches that would trap incoming enemies. They had other variants when geography made it convenient/necessary, such as the fortifications used in San Juan, Puerto Rico.
Castles and forts like these saw the end of their useful life when artillery shells first entered the scene (late industrial revolution in the Western World--around the time just before the world wars).
I also modified the Great Wall to have a more realistic useful life:
* Built with construction (not masonry)--the first major Great Wall attempt was that of the Qin unification (mid-classical era in 200something BC). Other smaller and less complex fort systems dated from before.
* Latest build being by the Renaissance (the most famous parts of the Great Wall date to the Ming Dynasty, which happens to be the Chinese period that was contemporary with the Western Renaissance).
* Obsolete with rifling (only do this on Legends of Revolution, when a similar wonder, the Brandemburg Gate, affects great general spawning rates).
