Tiny tidbits from a once local anon to this neck of the woods.
Circled used to be a civil attorneys office. The right side door that you can not see in the picture. This was back in early 2000s. That attorney went on to become a judge in Greensburg. Feliciani was the name.
The arrow is pointing to the courthouse in Greensburg. It’s down about a block and a half.
Can confirm there are tunnels and old bomb shelters in these areas, especially under the courthouse.
