Preexisting condition

Imagine if this tower had existed years ago
If it were around during our early wars as a nation
Think of the strategic possibilities in tow
The turning point of battles would be an inspiration
It would be a virtual fortress
Of concrete and rebar
British cannons would have little effect
On the reinforced structure
Its height would provide advantage
Providing a turning point in war
If this granary was around in 1813
I doubt it would be of an agricultural sort
I could see a general andrew jackson gleam
At the possibility of a great military fort
Then the friendly city would be known for more
More than just a new store surge
It may even have had a different name
It could have been called towerburg
