Hello,
Vincent,
Vincent and
Cooster ...
Thank you for sharing your afternoon project!
That's a beautiful fort! It could almost be any one of the forts built in the northeastern part of America.
This is a painting of the "Military Road" by Gary Zaboly. It shows many of the forts during the French and Indian War (Seven Years war) and the American War for Independence. Click on the painting to go to the website.

Thanks again and all the best,
Richard
