in 1779 as the first mercantile house in Nacogdoches. In 1902, it was dismantled, the stones saved, and the fort reconstructed on the campus
of Stephen F. Austin State University. Photo 1885.” ....... notice the primitive construction. The stone used is probably sandstone and difficult to cut. The Old Fort in Ohio is cut better, but the limestone there should be easily worked compared to any sandstone ~ you need a mill to run a saw to do it nice and neat.
I just posted it also....but didn’t realize that you posted it earlier. Anyways...I enjoy “the hunt”. Also took a stab at who might have built it and when.
