Sense Sonnet - Pumper

Wall for all Ages

For 16 centuries I've stood
Along a 4000 mile span.
The emperors thought that I could
Hold back invading hordes of man.
Mongols and Manchus did come through
When gates of mine were opened by
Treasonous acts as traitors do -
No further need to fortify.
So now I am upkept to please
The hordes of tourists who invade
With cameras and all "say cheese"
Upon me for memories made.

The Great Wall of China, I'll be
As long as there is history.
