The tour of the Bank was very interesting!
For as old as the place is? It is in surprisingly good shape!
A few small leaks in the roof but not what I expected I'd see.
Basement was dry and showed no signs of flooding. I get worse in this house!
The Vault is a 2 story 12" thick reinforced concrete Zombie Bunker!!

We did find what may be a sealed off room in the basement also.
I figure the Concrete Vault/End of World Bunker was an upgrade sometime after the 1878-79 construction of the building.
The sealed off room is behind it and there's a brick arched door that leads right into the side of the Vault/Bunker. Not into the thing just smack up against the side of it!

We found that going down the side tunnels.
Yep! It has tunnels!!! I even went out under the sidewalk in front of the building.
I was kind of given an offer of $8800 by the Realtor. I think he was getting cold as it was down around 20F here today.
I was dressed to explore in the cold myself and crawled or climbed everywhere!
