The octagon shapes means there are sides facing north, south, east, and west. Windows on the next sides allow light in during the Solstice or Equinox. It has a great history, too. Besides being a residence, it's also been a hospital, Masonic Lodge, and a safe house for Confederate Soldiers.
It's not shy on ghost stories, either, which is why we went there to investigate - though our only experiences were a motion sensor that activated on the third step up from the first floor, and simultaneous motion sensors lighting up even on request at the slave cemetery. From what I have heard, I expected a LOT more activity. We may have to go again to get anything happening.
On my way there, I saw a few peculiar things that were fun:
Pink elephant outside a liquor store!
Eventually, I reached the destination: Octagon Hall!
Lots of signed photos from previous visitors and
shows or podcasts who have been there.
Looking from the ruins of a slave quarters to the
field where the family cemetery and the slave
cemeteries are located.
Then, night fell and the investigation began:
Finally, while Barb and I visited the slave cemetery, across the way in the sheep field we hears howls, barking, yelping - it was time to go indoors! The howling, yowling sound was just different than I'd heard before. And, when we got to the house? It stopped.
