Here’s what I know. At one time, this door was in an isolation ward that was part of a Maine psychiatric hospital campus built in 1957. This particular building was built as a tuberculosis facility. The campus was later converted to state offices (for some reason, this gives me the willies). The key is on the egress side of a door that swings out into the exit corridor.
I have my theories about what’s going on in these Fixed-it Friday photos. What say you?
